this setting cannot be changed becayse your Apple ID is missing age information
I have had no problem until I updated to iOS 17.5
I opened Monster Hunter Now and it told me if I wanted to use Facebook to login then I needed to turn on tracking. I went to Settings > Privacy & Security > Tracking but I can not turn it on. I get the error "this setting cannot be changed because your Apple ID is missing age information".
I have checked on my phone and the website and my birthdate info is correct.
I tried turning my phone on and off and even looked under Settings >General > VPN & Device Management and there is nothing listed there.
I have not logged out and back in because the last few times I had to do that, I had to reenter some of my cards into the Wallet app.
