But I just got another email from Samsung Support with the following suggestion.   "I suggest you to sign out and sign back into the app. To sign out, select Settings [on Amazon account], from the left menu, and then select Deregister your Device. Close the app, reopen, and then enter your credentials to sign back in."   That worked!  I now have Amazon Prime Videos back and working. I'm unable to sign back into the app, going back to the app I get the same screen that doesn't provide an option for signing back in, just the same "amazon" screen saying to contact if there are problems. I also tried clearing cache via unplug, hold down on button for 20 seconds after turning off (or on).  So frustrating.  Please help. If I remember, when I wanted to sign back in on my TV after I derigistered it. I got a message with a code with instructions to sign in on my computer. ... View more

This has been going on for a couple of weeks now and is extremely frustrating. I have a $1000 smat TV with the Prime Video app, but it doesn't work and I have to watch Prime Video on my laptop.

I've followed all the suggestions, reset the smart hub a couple of times, changed the DNS from automatic to 8.8.8.8, unplugged the TV for30 seconds, made sure it's the latest software update, clicked Reinstall on the app.  Nothing works. We even have an older Samsung smart TV, Model UN50H5203AF, in a location with a weaker WiFi signal and Prime Video works on that one. But it has stopped working on this newer TV. ... View more
