WiFi connection issues

I've got some WiFi issues that randomly started since updating the watch. The watch is no longer able to connect to a WiFi, even though it finds it and have been connected to said WiFi before. I just get an error with the red ring, and that's it. 

Things I tested to solve the issue without success:

  • Restart watch
  • Restart router (just in case..)
  • Restore watch from backup
  • Connect via app
  • Connect via watch

Other than the WiFi issue, the watch randomly just freezes and gets unresponsive to the point that I can no longer use it as a daily watch.

Has anyone else experienced this issue? If so, have you solved it and how?
