My App Library changed today all the apps moved to (others) on the App Library so any one have a solution for this ?

Yes, I have a solution. I've tried it several times that my apps suddenly find themselves in the "Other" folder.

This happens because the App Library, for one reason or another, does not have time to load apps into the right categories. Maybe after an update. I'm not quite sure, but to fix it - turn off your iPhone, leave it off for a minute and turn it on again.

Then the problem should be solved.

Okay, an update should fix that too.

This is because I said that apps are not loaded into the right categories. I know it does not solve the problem here and now, but try to give it a day or two and see if it does not correct itself, also try restarting the phone once in a while.

Okay it tends to work. How long has it been like this?

Have you updated to the latest version? (iOS 14.5.1)

You are welcome.

The error will be corrected.
