I’ve just figured out a VERY annoying mystery and I’m pretty chuffed with myself. The iOS upgrade to v18 merged my qwerty (english) and azerty (french) keyboards into two “french/english” keyboards without asking me. Which made #duolingo almost impossible because typing and dictation language reset to english *on every single exercise*. No matter how many times I set it to french again. Très ennuyeux.
PSA: if this is borked on your phone, too, it can be fixed by re-adding keyboards in settings
