Thanks for the logs… 
Please do a ps -ef | grep -i plex
Is Plex running as plex or your username ?
(you are using the snap package)
Snaps have a lot of restrictions. We will likely switch you over to using the .DEB package or reconfigure the mount to work with the snap. (The DEB package is the best way)

PS: I’m very sorry for assuming you were using the DEB package. We could have saved a lot of time.
