Amazon Fire TV App Review
for those with issues make sure you are using the same amazon login as your firestick. i purchased two firsticks using my gmail email and they came registered to my gmail but I purchased prime using my home email and when I tried to use this app from room to room I had issues until support figured it out. works great no issues now.
Is working well for both voice search and using the keyboard, but I cannot see how to delete a paired device?? I have signed out, cleared cache and app data, also uninstalled and reinstalled and it still gives me the option of two devices lol. There is also an option (Recast) which is US only, why not just have a different US app, rather than making me choose a selection just so I can use the app!
