I can't seem to get custom sorting to work for my movie collections. Every time I move the movie into the spot I want it doesn't stay in place and just moves back to where I originally had it.
I have tried this on Edge, Chrome and Firefox and no browser seems to work. I am on pre-release Version 2022.07.06.1622.
UPDATE: After playing around with this a bit more I finally got it to work.
The collections that I was having issues were collections I had created a few weeks ago. After I had created those I had removed my movies from Channels and re-added them later. Channels keeps the collections in place and you just have to re-add the movies to the collection if you do this.
When I deleted the originally created collection and re-added it I see that manually moving the movies around works now.
