AppleID password not accepted for signing in to iTunes store to update apps on iPhone X
I am unable to update apps on my iPhone X because when I enter my AppleID password to the "Sign In to the iTunes store", I get the message "Apple ID Verification Open Settings to continue signing in with abc@thing.com" (where "abc@thing.com" here is just a fictitious email address I made up for the purposes of posting this question). I know that the AppleID in my iPhone settings and the AppleID password I entered at the prompt above are correct because I can use them on my computer to access my AppleID account. I don't understand why I'm being asked to sign in with an old AppleID abc@thing.com. How do I get whatever software is involved to accept my current AppleID and password? I don't see any way to force it to do so.
