@kozec I’ve a technical question for the Syncthing Android app.
When I put the “only on wifi syncing” turn on on the Android app. Then the app is completely switched off until a wifi connection or discovered, or is the “local discovery” still active?
If you are referring to the official Android app (https://github.com/syncthing/syncthing-android), you pinged the wrong user. This one is maintained by @Nutomic.
As Synthing itself does not currently have the features needed for this functionality, the App shuts down syncthing completely when not on Wifi.
