We are sorry to hear about this. Can you provide the full model number for the television?
Instead of opening a new thread for similar issue I decided to add my issue to this one. I have the same or similar problem in that I can only load one photo at a time. My TV model number is QN65Q90RAFX
I have the same problem as the prior post except wanting to alternate the TVs artwork rather than my own photos (model 75" Q60). It's really annoying that I have to manually change the artwork in ambient mode. With all the amazing technology the TV has this small feature should be so easy but is so annoying that the TV can't do it. If someone has figured out a way, please let us know.
