Other apps work, only 4K on Amazon is broken. It doesn't load, and I get the generic "Something went wrong Please try again later. For more help, go to amazon.com/videohelp." garbage.
/r/ShieldAndroidTV is all of a sudden restricted from new posters. What is going on?
This has been happening to a lot of people for a few weeks now. You can see a thread on the nvidia forums and others here.
It had actually been working for me until yesterday's update of the prime video app. Now it doesn't work for me either. Amazon are going the opposite way with their "fixes"!
4k and HD is being restricted on certain platforms
I had this problem last night. I tried changing between all available 4k resolutions. The 24hz and 59hz selections did not work, but the 4k 60hz selection did work. YMMV.
I had the same thing happen the other day. Amazon's Prime apps are garbage in that they have two versions of every show. I had to search for the non-4K version of the show I wanted to watch for it to work.
I am in the UK and have no issue whatsoever playing 4k on either Amazon or Netflix on both my shields (2017 and 2019), not sure if the EU restriction applies or not to the UK though as we are in the transition period.
Is it wired directly to your 4K TV? Or through a Surround Sound receiver? Ive got mine through a receiver and it doesn't support 4k resolution. I have to connect the shield directly to the back for 4K streaming.
Europe has a broadband shortage so all streamers are going back to SD quality.
