I cant get spotify to recognize that i have a premium acount on my rocu tv i signed up on my computer but ther seems to be no way to get them to recognize it on my roku tv
Have you tried logging out of the Spotify app on your Roku then enabling it again?
Click Account on the menu down the left side, the click the FORGET ME ON THIS DEVICE button.
Now click LOG IN on the next screen, and follow the instructions to go to your Roku.
