My  2022 frame was purchased today and now is stuck on an art work, none of the buttons on the remote will do anything apart from the on off button, “Not available “ comes up when some are pressed. 
Before it froze, it would not go into the art section on the Home Screen, when selected, it would either go to Samsung tv or to the last viewed app. 
many help would be appreciated.

I am in Australia if that matters 

thanks
