@david I assume it’s not #ivory but iOS / macOS doing such corrections/replacements depending on context. I think it’s a default behavior of edit fields. Not sure if it’s possible to turn of just specific behaviors - probably turning of all automatic is possible but then no autocorrect would be there at all not sure if this would be a good thing or not
If it’s @ivory doing it by itself I would be surprised but it would be very interesting how they do it
