Does Syncthing on Android distinguish when it’s roaming or local?
I’d like to turn it on when in my own network, but I’m super afraid I’ll accidentally leave it on when I happen to travel abroad.
Is this something that’s already supported, perhaps? Would this be a reasonable feature request?
I’m pretty sure there is no special code to handle this.
You should check for existing issues in the android repo, perhaps this was asked before, if not, open a new one, but given the app in maintenance mode, I wouldn’t hold your breath.
That’s where I came from. It was the new issue template that redirected me here. 
I did take a look around, found no issue mentioning this.
Okidokes, will continue this there!
