I completely agree. I thought Plex would be fast in the collective rearview mirror as soon as they started forcing connections to their servers, pay-walling, etc. I also had issues with the database corrupting and causing huge slowdowns. I spent days trying and failing to preserve my ratings, watch data, etc.

In the end, I switched to a much simpler setup of an NFS/CIFS share accessed by Kodi on my Nvidia Shield TV. If Kodi chokes (happened once since 2017), I can just wipe the app and/or reinstall and then import the local metadata (XML or NFO IIRC). That takes about five minutes. It just works. Kodi also gives me access to the IAGL, so that’s a huge plus.
