ALL and @VipeNess
The hiding of the Plex icon feature, which I gave us here,
has been removed / withdrawn
The capability is not working as Synology documentation describes it.
It is causing more confusion than it’s worth.
For these two reasons, I’ve decided to withdraw it and make the Plex icon always visible to all users.
If I could make it work correctly (ON by default for ALL users) then I would keep it but that’s not how it’s working out.
Synology says it should work but it’s not — So out it goes.
I apologize for the confusion and inconvenience.
The icon will be visible again in the next PMS release (1.40 AFAIK)
