Plex Files Unavailable but they’re not missing

I’m using a Mac Studio M2 Max with 7 Synology 1821+ NAS connected via SMB. Only two of the seven are affected. It’s just my TV Shows library. They’re each connected via Finder, and to keep them connected I also user AutoMounter. But I’ve tried various ways to connect, even turning off AutoMounter to see if it was that. Reset the keychains. Changed my passwords so it would force a new prompt to sign in. Same behaviors.

Plus, the other five are used for my Movies library and they all work as expected.

And all the Unavailable files play thru the Mac desktop Plex app, but not my iPhone, iPad or Apple TV or my remote users. But Infuse plays those same Unavailable files thru all those devices without a problem.

Staff simply needs to be made aware of the problem and it’s likely a quick fix.
