Yes, I did that as well. A message appeared to say that the restart was successful, but it still doesn’t work. I just tried it again and got the same result- success message but no connection.
You should not need to follow the temporary solution listed there as we believe the problem is fixed.
However, you may need to reboot the camera. You should be able to do this via the settings page (live stream > gear icon) in the app, even though the live stream is not working.
