Trusted Devices list is not available - iphone 13
I am not able to access several apps (Audible and Amazon) from my iphone. They work fine on my ipad. I see in settings->Apple ID that where I should have a list of trusted devices there is a message "trusted devices lists is not available"
My phone and watch are listed as trusted devices on my ipad, and on https://appleid.apple.com/
The whole Apple ID page is non-functional on my phone, so I can't sign out, or get into password & security, etc.
Somewhat ironically, two-factor authentication requests are still being sent to the phone.
I've done 3 restarts in the hopes that it would solve the issue.
iPhone 13 mini, 15
