I'm sorry but you don't seem to have any media in your plex server
Ive just linked up an Echo Dot to my plex library and not having much luck so far.
First it said it had problems connecting to the skill right now, b ut i think that was because my server was running a vpn client. ive disabled that and it kind of work now for some commands.
So saying, "Alexa, ask plex to play music by the chemical brothers" sometimes works, but asking much else I get "I'm sorry but you don't seem to have any media in your plex server"
I obviously do have music and movies indexed and working fine, but Alexa thinks I do not.
