I am having an issue with an iOS application which doesn't allow choosing between configured iOS keyboard languages except for English and Emoji
The very same app (in this case, Bolt) shows the language selection normally on my wife's device.
I've had the issue before with some other apps, but that happens rarely so I don't recall which apps they were. In either case, it doesn't seem a problem with an app, as on other devices the language selection looks fine.
Here is the screenshot from Bolt and Uber, running on the same device.
I have searched the internet but couldn't find other reports of the same issue, probably due to many other topics around the same keywords.
