Are you getting the error "Prime Video doesn't support your web browser" or "This video is unavailable to watch on this device." when you go to rent or purchase a show on your Android or Apple phone or tablet?
This error is coming from Amazon. Amazon appears to have an issue with certain devices or web browsers using their mobile app. To get around this error on your mobile device, you'll need to exit the VidAngel app and not use the Amazon mobile app but go directly to www.amazon.com on a web browser instead to rent or purchase your movie.
Be sure to log into the same Amazon account that is connected to VidAngel. Complete the rent/purchase of the movie (make sure to get the theatrical version) and then refresh your VidAngel mobile app to continue watching your show.
