My phone stopped automatically backing up around 2 weeks ago
I didn’t realize my iPhone 12 wasn’t backing up until I received a notice in settings. I did a manual backup and received an error but it worked after I rebooted however it won’t auto backup overnight anymore. I haven’t made any changes or deleted old iCloud backups. I have more than 1/2 available iCloud storage remaining. It used to backup over night when my phone is plugged in. My Wi-Fi hasn’t changed. Any idea what happened and how to fix?
iPhone 12, iOS 15
