I have been going in circles with Portal Support via e-mail and they keep directing me to this black hole.

The ambient slideshow needs to use ALL of the photos placed in an album, not just the 50 "most popular". There should not be an algorithm choosing which photos show on the slide show unless someone chooses that specifically. I have this device for my 97 year old grandfather and the album is private and intended just for him to view. He only sees the 50 most recent added photos because of this algorithm/popularity contest. 50 photos does not begin to scratch the surface of 73 years of marriage, children, grand children, great grandchildren, parents , siblings, war buddies, life long friends, pets...The 400 I have in the album barely scratch the surface and he can't see those because someone decided that the photos you see on the ambient slideshow need to be popular to other people and interacted with.
