Can‘t update any iOS Apps: “If you have an Apple ID, sign in with it here“ Edit: I did a factory reset and it worked. Very annoying bug...
I haven‘t been able to update apps in months. Whenever I click on update, the App Store prompts me with:

“If you have an Apple ID, sign in with it here.“


Not only am I already logged into my account (yes, it is the same account that I used to download the app), there is literally no way I can log in with this prompt, since it asks for only a password and not an email + password. Whatever I type in, I get “Your Apple Id or Password is incorrect.“
Here‘s what I‘ve tried:

Updating iOS

Restarting iPhone several times

Logging in and out of different Apple Accounts


Does anyone have any ideas on what I should do? Anything I’m missing?
I haven‘t really cared much but now WhatsApp is forcing me to update and refuses to support my version so I literally cannot use it. I also don‘t want to delete and reinstall it because I would lose my chat and document histories.
To anyone having the same problem, the only thing that worked for me was doing a full reset.
