RS, Author, Novelist, Prosaist<p><strong>PSA: The Mastodon web app (web UI) v4.4.5+glitchsoc does not work well with iOS 26 or iPadOS 26 (see bug list below).</strong></p><p>I'm including the GlitchSoc devs as well as Mastodon devs in this report, as I can't test without glitchSoc because of my instance. I am not using advanced mode. These bugs become increasingly obvious with minutes of use. I acknowledge these may also be Apple Webkit bugs, but web developers know that you still have to make your app work despite the bugs by version conditioning ame workarounds, and by reporting them on a dev account Radar. </p><p><strong>I cannot recommend the web UI until these bugs are fixed; a Mastodon app will save you frustration.</strong>*</p><p>Please boost for visibility.</p><ol><li>On iPhone, the Mastodon app bar at the very bottom does not stay at the bottom. As you scroll longer posts, it drifts upward or downward. This looks like a basic div error where the div isn't fixed in place once the iPhone screen is measured. It ends up covering other interface elements.</li><li>On the iPhone, probably an extension of item 1, the toot button bar ends up hidden under the app bar when scrolling in larger posts. Scrolling to show it (hindered by item 1), causes it to rise small increments until it is visible.</li><li>On iPad, after a short while of navigating, the web UI forgets the screen size (or doesn't properly understand signals from the iPad) and seems to zoom toward the upper left, clipping other content. This requires pinching to zoom out to again make the full screen usable.</li><li>On iPad, after some use, the web app develops a tap offset. You click one place in the edit control and though the cursor shows there, the insert point is somewhere below. In non-entry fields, you can't directly click buttons. In its worst manifestation, when you display the post menu … button and try to tap Edit you end up tapping Delete.</li><li>The web UI arbitrarily and intermittently resets or refreshes the screen when navigating left-side contents, erasing the contents of the toot entry field. You must type Select All and Copy before tapping buttons or links or even unexpanded toot text left of the entry field.</li><li>On the iPad, buttons and links stop working. You can hover over or tap them and see them react, but they do nothing. For example, you can't get the POST or UPDATE buttons to function. This isn't the offset problem above. This requires restarting the page by closing the tab or force quitting the start page web app. At least you can copy the contents of the entry field when you have been caught typing into it.</li></ol><p>These problems showed all during the public beta of iOS and iPadOS 26, and only in Mastodon Web UI. Q/A testing for a major platform appears to have gotten short-shrift.</p><p>I am using both a Safari tab and the Safari page saved as a web app on the start screen. The issues show up in the original full screen windowing, and both of the stage manager and new windows manager scenarios. It is an ubiquitous bug.</p><p>PS: If you know how to submit the issues directly to the devs administering the web UI projects, please reply and I will forward.</p><p><a href="https://eldritch.cafe/tags/BoostingIsSharing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>BoostingIsSharing</span></a> </p><p><a href="https://eldritch.cafe/tags/glitchsoc" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>glitchsoc</span></a> <a href="https://eldritch.cafe/tags/mastodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>mastodon</span></a> <a href="https://eldritch.cafe/tags/bug" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bug</span></a> <a href="https://eldritch.cafe/tags/bugs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bugs</span></a> <a href="https://eldritch.cafe/tags/fediverse" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fediverse</span></a> <a href="https://eldritch.cafe/tags/apple" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>apple</span></a> <a href="https://eldritch.cafe/tags/ipad" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ipad</span></a> <a href="https://eldritch.cafe/tags/iphone" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>iphone</span></a> <a href="https://eldritch.cafe/tags/ios" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ios</span></a> <a href="https://eldritch.cafe/tags/ios26" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ios26</span></a> <a href="https://eldritch.cafe/tags/ipados" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ipados</span></a> <a href="https://eldritch.cafe/tags/ipadOS26" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ipadOS26</span></a> <a href="https://eldritch.cafe/tags/webapp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>webapp</span></a> <a href="https://eldritch.cafe/tags/writer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>writer</span></a> <a href="https://eldritch.cafe/tags/author" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>author</span></a> <a href="https://eldritch.cafe/tags/programmer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>programmer</span></a> <a href="https://eldritch.cafe/tags/code" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>code</span></a> <a href="https://eldritch.cafe/tags/writingCommunity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>writingCommunity</span></a> <a href="https://eldritch.cafe/tags/writersOfMaston" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>writersOfMaston</span></a> <a href="https://eldritch.cafe/tags/Bookstodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Bookstodon</span></a> <a href="https://eldritch.cafe/tags/psa" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>psa</span></a> </p><p>I am cc'ing you in the low chance this is an instance issue.
