Okay, strangness. I updated from a Samsung note 9 to a samsung note 10. No problems with smartthings - almost everything works on the note 10 EXCEPT my three thermostats (1 ecobee and 2 ct-100’s I believe).
When I click on any of the thermostats, same results. They show the current temp up top, what the heat is set to, what the cool is set to and the “idle” button. But nothing else. When I open the smartthings app on my note 9, everything works… ideas/
