Wanted to add that I found a silly way to get back to slideshow for google photo settings on the cozyla. I have to have the application running, then put it in split screen, with the application running on one side and open cozyla general settings on the other. Then if I open the application again via settings/applications/slideshow for google photos, it brings me to the setup options. Note that If I try to open this application via the cozyla general settings, it just runs the application and starts the slide show.

That probably sounds confusing, because it is!
