Just to verify though, the latest public version though, correct? Because otherwise, they would have potential users trying to use the plexpass versions, but couldn’t due to not being plex pass members.
Your login activates plexpass features, not the download. Plexpass download is really just pretesting the next intended version, bugs and all. Best to run public unless you are use to finding issues.
Edit grammar
But, this does not seem to activate downloading the plexpass versions: Version 1.19.3.2764
Is what I received after re-running a run for plex. The latest plexpass version is: 1.19.3.2793-36efde971
There does not seem to be an env variable exposed either to specify the use of plexpass versions over public channel.
If the tag is set to beta and the Server Settings > General > Server update Channel is set to beta then it should notify you of a beta version that will pull the next time you restart the docker.
Search ‘Plex Media Server.log’ for PUT /updater/check?download= to see it version check.
