TRIP+ members, how do you get your Spotify synced to the TRIP+ feed and how do you join the Discord server?

Title. I bit the bullet and subscribed to TRIP+ premium but the instructions are pretty average and although my Spotify is apparently synced up to TRIP+ I can still hear the adverts in the beginning of each episode. And there are no instructions on how to access the Discord server despite saying that they encourage it. Can someone help me out?
