I would say I do see a roadmap. But can only guess why the changes. Maybe:
- Plex wants dedicated apps for each media type, removing old code and making the apps easier to update and maintain.
- They want to redesign the Plex experience by updating the UI, functionality etc.
- Keep the Plex ecosystem growing (they have talked about opening up 3rd party agents and NFO support which has been a long requested feature).
Of course with change and redesigning things you will undoubtedly get pushback, but to be fair the change and redesign was much needed on some platforms like the Apple TV.
I hope Plex communicates better which features they plan to leave behind, and which features will be added back to the new experience apps over time. I think that would alleviate a lot of concerns.
