i am having a heck of a time viewing my selected videos after following Amazon's posted instructions for installing the Prime Video App after installing (or reinstalling for that matter, with the proper permissions) the Amazon App Store. I merely get the instruction page to pop up again after I think I have done everything correctly and click the "play video" link. . Has anyone gotten this to work on a tablet other than a Kindle??? Frustration abounds! Thanks for any help you can offer!
