Although I have language values for French, german, Italian, Spanish and now Ukraine in my app, French users are reporting that the app no longer presents in French.
This is a relatively recent thing
Whats changed at my end:
Switched to App Wrapper 4
Switched to Big Sur
Added Ukranian language defs
When I go to my system prefs, add French and make it top of the language list, the app works in French for me.
What can I check?
