My smart things app is connected to my Samsung Q60AA 75” tv. However when I click on the ambient mode on the tv, it only shows that the tv is in ambient mode on the app and no where to upload or change any photos. There’s not even an option to click on ambient mode, it just says the tv is on ambient mode. Please help. It worked when I first set up the tv, however now(3 days later) I had to re set up as the app wasn’t working and now ambient mode won’t work.
