Unfortunately ATM I cannot be of great help on these use cases.
Currently my main desktop subsurface is behind a proxy and git cloud
connection doesn't work (I posted about it months ago but I understand
that I'm a corner case) so currently  I have mainly access only to
Subsurface mobile and I'm afraid to delete my logbook so I'm always
very cautious doing experiments. Occasionally I use another desktop
connection just to save my new dives.

I agree that a normal user gets confused on which side is updated
while syncing to the cloud. While using GIT for cloud logbook is
really a unique feature, we cannot pretend that the average joe
understands it.

Let me see if I find some doc specific to mobile apps...
