The worst part is having to send a technician all the way to Washington to reset the system. Do they still have anyone posted on the detail who is closer than Moscow or Beijing?
(quick edit - I’m making light because it’s political, but I legitimately sucked in a breath when I saw it happen, as both my father and FIL are in their 80s and I’m not ready to lose either of them yet.)
If you pay the one time fee or the subscription fee, the system unlocks all the paid features for all of the users on your account. Under your account you can have multiple users, each with their own viewing history (and restrictions, iirc). So if your users log into Plex on their devices using your account username and password - abbadon420 and Hunter1 - and then select their user profile, they will all have access to the features.
The one time fee unlocks forever (the lifetime of Plex, of course) and the subscription unlocks the features for the term of the subscription and then you revert back.
Bluetooth for audio might be the worst implementation of a specification every devised. Ridiculous lag, no multipoint connection, no ability to manage or negotiate connections from the device, limited ability to define the connection (audio vs headset among the culprits). BT for audio just seems like a cruel joke.
So…does it allow you to eventually download the files, or are you limited to simply streaming from the remote cache?
