I recently registered for Amazon prime. I added the channel to my roku device, has no issues signing in, but it is showing an additional cost for every single movie or TV show right now, even ones that are not suppose to have an additional cost when you have a membership. If I go to a different TV and log in not using my roku, this additional cost isn’t there. Anyone have any idea why this is happening when I stream through my roku? Thanks! #amazonprime
Did you ever sign into your account Prime Video app on the Roku? Until you do it can't give you your Amazon Prime benefits.
Click Sign in in the upper left corner and log in using your Amazon account credentials.
If you have already signed in, see if signing out and back in fixes things. To sign out click Settings in the upper right corner, then scroll down and click on Sign out.
Now click Sign in in the upper left corner and log in using your Amazon account credentials.
