iMac 2019 MacOS Mojave; iOS 15.7.1
Sometime after I updated my iPhone 8 and iPad (9th gen) I get a message on the iPhone/iPad every time I connect via USB to provide a passcode to back up the device.
"Enter passcode to Start a Backup"
On the iMac I get the following message about the passcode requirement with the choices Cancel or Try Again.
"iTunes could not back up the 'device' “device name” because it is locked with a passcode. You must enter your passcode on the 'device' before it can be backed up."
I believe the behavior started with iOS 15.7 for both devices.
I tried both settings for the "USB Accessories" preference under "Touch ID and Passcode" without success and I couldn't find any information about this change.
Any ideas how to turn off this persistent passcode prompting without disabling the passcode?
Edit: Devices are synced if Cancel is selected for prompts, just no backup.
