Can not open Syncthing

Hey guys I’ve been having a problem I can not open synching when I open the app nothing happens except the loading screen it just keeps loading there’s no end to it. I will try my best to explain this problem. Android Version: 6.0 App version: 1.27.6 when it happens: every time I open the app

Here is syncthing app log

sorry, I forgot to tell you this but this whole problem started after I scanned the QR code ID of another device.

Android 6 is a fairly old version. I think you’ve got the same issue as described in the following earlier forum thread: https://forum.syncthing.net/t/can-not-open-syncthing/22288

Mostly likely just a coincidence and unrelated.

UPDATE: This issue persisted, and I wasn’t able to resolve this issue. I think this is some app-related bug. Solution or workaround :slight_smile: I just installed synching-fork from F-droid which is a synching client and it worked.
