I’m getting trouble signing into App Store?

Do you have access to another WiFi network where you can try? That has worked for several people.

Try a restart.

Restart your iPhone, iPad, or iPod touch

Try a forced restart.

Reset Device

Device or computer? What happens when you try? Error message(s)? More information would help.

After I updated my iPhone yesterday it kept asking me for my apple password. I logged out of everything & then logged back in. I was able to login to iCloud without a problem however I can’t login to iTunes or the App Store. It looks as though it is logging in but nothing happens.

A hard reset did the trick! Thank you!

Both of you are welcome.
