I have a large playlist with about 990 items in it and when shuffling this on Emby Theater on my Xbox, the first episode plays, but the next episode never does, and all I get is the spinning circle and a black screen. The same happens when hitting next as that also gives me the spinning circle and a black screen.
The same playlist plays fine on the beta Shield app and my android tabled.
After reducing the number of items in the playlist to about 300, everything works fine..
server version is 126.96.36.199
app version is 188.8.131.52
Xbox is on insider build but I'm not sure if that is an issue here.
Can provide logs if needed but this should be easy to reproduce.
