In general I’d agree but moving forward should be raid. If you fail you rollback, fix and then rollout again. Simple 101 agile development.
Unfortunately plex have proved in the past they cannot do rapid development. Maybe this time I’ll be shown to be wrong but I suspect it’ll be 2021 before we end up with any sort of parity for functionality removed by this update not to even mention a polished UX experience.
As an example and why I’m skeptical, this was a regression introduced almost a year ago now → TVDB Episode 'Directors' Metadata not downloaded to Plex and I’m still waiting on a fix. And yes a regression! Was something that work, they change the UX and it broke it and has never worked since. I’ll be dead in the ground before a fix will come.
