I’m having a similar issue. Everything runs through fine, all the devices are seen, the users are seen, I get to default temps (18 for heating, 0 for cooling since we have no cooling devices) and default overide (I’ve tried manual and tado_mode). Everything appears normal. However, as soon as I click done I get a processing message as Alexa is recognising the rooms, but SmartThings reports “We’re having trouble connecting. Check your network connection and try again”.
I’m so close… Any ideas?
