I have an nvidia shield.  Last night I tried to watch Playstation Vue and it complained that there was an update available, I went to the store and there was no update. This left me unable to use it.  I cleared the data and uninstalled the app.  I then tried to reinstall the app and it wasn't in the play store anymore.  I went to web version on my desktop play.google.com and can see it and I hit install, but the shield is now not a valid device, nor is any of my other android devices.  Thoughts?
