Apple TV no longer permits changing slide show duration
I cannot believe that Apple has removed the longstanding ability to choose how long to see each slide in a screen saver slide show. This was a feature for many many years. To make matters worse, the default (not changeable time) is just a few seconds now.
I spent almost 40 hours preparing a slide show for Thanksgiving, and also for Christmas where we are hosting from our safari trip to South Africa in October, and the photos are scrolling away faster than anyone can look at them.
PLEASE restore this feature. Apple does not know best here - we should be able to adjust the per-slide time based on various factors. We own three Apple TV 4Ks. Also, apparently after much searching it seems Apple also does not allow 3rd party slideshow apps, at least I can't find any in the store. So there is no other good way to do this.
I do *not* want to Airplay this because these are very high resolution HDR photos of wildlife taken with a large megapixel DSLR.
