I spent all day today trying to replace my favourite photos in the photo Board on Ambient Mode..... After gaining a new way to play your own music whilst in ambient mode (connect your phones Bluetooth to the TV whilst your listening to whatever app or stored music, its BRILL!), however somehow I disconnected my user account on the TV??? And didn't know, and all my ambient board photos disappeared too. So the mission began between the smart things app and my TV, unbeknown to me I entered the wrong email account into the tv, smart things worked fine on every other device, so after much swearing 🤬 and hair pulling 🤯😱😭😱🤯 disabling, reinstalling, emptying caches etc etc, you get it🤔 finally I changed the tv email account that matches the phone and hey presto... 🥳🥳👌 job done.
Hope this helps you?
Ps, try the music whilst in your choice of ambient mode 👍
