So, this cropped up a few days ago, haven't had a chance to check into it until now. As far as my searching of this forum went, I don't think anyone has reported what I'm seeing.
When trying to scroll through my tv/movie/etc lists, I can't. I can tap the letter menu and jump down, but the normal swipe to scroll method fails.
It appears to be a Firefox specific issue. When I pulled up Chrome (for the first time in a long time...) it worked just fine.
Emby server is 18.104.22.168 running in Docker on a linux host.
Firefox is on Android, version 68.4.2.
Android is version 9.
Only Firefox add on I have enabled is uBlock Origin, which has a nice (0) next to it, so it isn't blocking anything.
If this would be better as a GitHub issue, or posted in a different forum, let me know. This seems like the correct forum....
