I'm using French and English (both Canadian) as a bilingual keyboard (which is new to iOS 18) that allows one keyboard to work in both languages - in opposition to the older way of doing it (having 2 keyboard -- 1 per language -- and autocorrect working in both languages). Having both French and English on the same keyboard allows to choose any supported layouts but this time, QWERTY with accent -- really optimized for French -- is not available anymore, only regular QWERTY shows up. It could be a bug or a feature, but it's preventing me from using the keyboard. I had to revert back to two distinct keyboard (1 per lang) -- but they seems to have removed the autocorrecting bridge between both language, so I need to switch keyboard to switch language autocorrect. It's not a show stopper, more of a quality of life degradation.
