iPhone Sync settings keep changing (and other weirdness)
Just upgraded my computer to Catalina. Now when I try to set my phone's sync settings through the finder, they won't stay consistent at all.
For instance, if I click Backup to this mac, and then tell it to back up, it will do it, but then the setting reverts to backup to icloud. It also keeps turning on 'sync photos to my device' no matter how many times I turn it off and apply. It wipes out all my books, but I can add those back via sync. For a little while I had the option to 'manage storage,' but now that's disappeared as well.
What on earth is going on?
iPhone 8, iOS 13
