That surprised me, too. A while back they nerfed some feature in Video Station, their IMHO crummy Plex analog. Wow, did people ever get bent! Meanwhile, I didn’t know anyone actually used and liked it. It worked alright but the client apps were/are a giant leap behind alternatives for Plex or Jellyfin.

But no, the built-in option seemed to have a league of fans in the Venn overlap of “people who want to stream video off their NAS” and “people willing to settle for an oddball solution”.
