Something happned with my marketplace it Just emty
Any ideas ???
- iOS or Android?
- Did you update to the latest App version?
- Clear your App Cache / logout / login
Mine still has plenty of entries (Android).
I have IOS and am a brand new owner of Smartthings hub… have tried login logout many times but no luck… Its getting fustrating when you want to play with it and it does not work
