iCloud password won't work on App Store
My iCloud password works when I log into iCloud.com, but it won't work when I try to sign in on the App Store. I changed to a different PW, and it works fine everywhere I need iCloud connection, except the App Store.
When I try to sign in to the app store, it sends a confirmation number to my phone, so it is trying to log in.
