Instead of Verification Code Ask Me to Change Password
Have iPad Air and iPhone and two-factor enabled on one single icloud account. Try to Install Zoom from App Store on iPad, input password for Apple ID, it said send a verification code to iPhone. But what iPhone got was:
Change Apple ID Password?
If you think someone is trying to sign in to your account, you should change your password.
Not Now Continue
First I chose "Not Now", it disappeared and nothing else come up, and iPad won't continue installation. Off both for 2 minutes, turn back on, repeated same on iPad, no more msg got on iPhone.
Two days later, I chose "Continue" and change password, reboot both again. Wait for a day, still getting the same "Change Apple ID Password" and no verification code.
A day later, I added a phone number under two-factor verification, this is a real number of an Android. It was successful. Reboot both iPhone and iPad.
Yesterday, thought all set, still receiving the same on iPhone, and nothing on Android phone.
