Does anyone have a succint, current, what-the-hell-is-going-on summary for #syncthing on android?

I know there were a bunch of issues, and even what some of them were. I'm looking for current recommended practice, which of the various forks to trust, etc.

I have longer term plans involving nix-on-droid to manage configs and switching off android entirely (for some devices) but that needs more preparation and testing.

For now I just need to get syncthing working on a new device the same as all our others, including having it start automatically on boot (as the most useful aspect of the wrapper)
