I find plex unusable since the latest UI updates in any place but my PC browser. It's so slow that Jellyfin is really my only option now. Did the vibe-code the new changes or what?
The new UI version never made it to the Xbox client so that's what I switched to using about 6 months ago. As a bonus, I got to ditch my Roku altogether.
There seems to be widespread disdain for it. AFAIK they switched to a shared codebase to make it easy for the devs to deploy to multiple devices. But, it came at the expense of UX for pretty much all devices. They don’t use native video services on things like iPhone.
