I've been using Trelllo for years and have had no problems updating boards with photos. for over two weeks, the boards try to update / sync and they spin for about 2 seconds and then stop.
Sync logs mention waiting for phone to cool down, but I have gone back in when phone is cool and not being used and same thing and boards have not updated since end of July. I don't want to close app or log out as I will lose all current photos uploading.
I have turned phone off and on. I have closed app several times and reopened when cold and able to update without overheating issues.
Nothing is working.
