I've been able to back up my Pixel 6a to a flash drive a couple of times now. But after updating to Android 16, it gets halfway through backing up, then my VPN disconnects , and it says Backup not complete. Using mobile data? Connect to WiFi and try again. Usually it backed up fine over mobile data. But I connected to WiFi and the same thing happened. So I completely disabled my VPN, but it still didn't work. Any ideas on what's going on and how to fix it? Thanks
