I've been using Team Tracker on Edge for a couple of months and it has worked well. Suddenly, today, when I go to the dashboard it says the Team Tracker Card does not exist. It works OK on Firefox and iPhone. I first noticed the problem after a brief power outage. I have restarted HA and have attempted to find where to go to restore from a backup a day or so ago, but I couldn't figure that out. Any suggestions?
I noticed that @wanton zinc had a very similar problem in June: Did you find a solution?
