I also have this problem, kinda. After some analysis runs with server 1.11.0.4633 all of my tracks before a particular album by an artist starting with B have loudness data (about 1/5 or 1/6 of my total library by albums), but all tracks after don’t. Manually analyzing specific tracks doesn’t fix this either. I’ve tailed the log during analysis and verified that the server scans my entire music collection without issue, but I don’t see any data about loudness gathering so it’s unclear to me where this is failing. It might be working fine but for some reason PlexAmp isn’t getting it?
