I use Plex on webOS and Windows (HTPC) and both versions of those apps are basically functionally identical. The issue is that the app version for Fire TV (I have a 4k Max) is missing the delete season function which is available on the other platforms.
My specific tv watching habit is to watch a full season before I delete episodes for content I am not collecting. Since the delete season is missing I have to wait until I am logged into one of the versions of PLex that does support it until I can remove the watched content as deleting 12 episodes one episode at a time is tedious.
