Announcement by the creator: https://forum.syncthing.net/t/discontinuing-syncthing-android/23002
Unfortunately I don’t have good news on the state of the android app: I am retiring it. The last release on Github and F-Droid will happen with the December 2024 Syncthing version.
Reason is a combination of Google making Play publishing something between hard and impossible and no active maintenance. The app saw no significant development for a long time and without Play releases I do no longer see enough benefit and/or have enough motivation to keep up the ongoing maintenance an app requires even without doing much, if any, changes.
Thanks a lot to everyone who ever contributed to this app!
My primary phone belongs to my work. I get a stipend every two years that essentially allows me to buy any supported phone I want.
The conditions are that it’s managed by them via MDM and all my work stuff is on the work profile side.
It is a choice I make since it allows me to not carry two phones. I did that for the first two years at my company and it was annoying.
So it’s not yours. Looks from here that’s the one issue you have to solve before everything else.
