Hi Renate,
Thanks for the assistance and suggestions.
Regarding, `Content/Android/data` ... it appears that's simply how the `/data/` folder was being presented in the Android file app I use on MacOS. Looking on the folder tree on the device itself, I can see it's the `/data/` folder.
I've now done a full backup using ADB.
If I end up needing to do a restore, it will be interesting to see what actually restores. I've read online that ADB restores some, but not all, things on Android devices.
