Critical app is rejecting password on new Apple iPhone. Also need to revise device name that worked carrier transferred over without checking with me to see if I wanted to revise it. (Keeping same email as Apple ID.)
Which should I do first?

For app issues, you may need to contact the app developer.
*”worked carrier” should be “wireless carrier” — AI is cracked!
