I've been using the fdroid syncthing-fork version for a long time now and haven't had any issues at all... Doesn't mean it'll last forever but it's been getting the job done for me even in its current state.
... And can't remember my original reason to use the fork instead lol
To be fair, this is true for Windows and Mac too, unless you aren't counting the simple scape goat of wiping and reloading lol
