Looked in to it a bit last night. A lot of the problem is Android 4.4 and newer specifically stripped out the underpinnings for Flash. This makes sense, Flash hasn't technically been supported in Android since 4.1 launched, this was a decision made by Adobe back in 2011 and executed in 2012 when it stopped producing Flash for mobile. Since then, Google has largely been building Android's underpinnings around Linux, HTML5, and Java.
So Amazon has to be running some kind of mutant custom build of the flash player on its Fire devices, since everything I read says that the app itself relies on it and many f amazons videos are still in flash. (which is asinine when even youtube has switched largely to newer open formats like webM and HTML5 VIDEO for many of its videos and its library is easily ten times the size of Amazon's)
If you've tried Dolphin, and you've tried the hacked flashplayer, then you've tried all the solutions that I found. The articles I read said they only work on certain 4.4 devices anyways, because Adobe only has a few flash-certified android devices on its list: IE the ones who have been built with the Adobe Flash code reinserted into their firmware. It seems that, according to some articles anyway, that the Amazon Player apps call home and get a hardware list from Amazon, and blacklist anything classified as a "tablet," but will still work on most phones. This means that even if you use some tricks like side-loading the phone version of the app (installing remotely form your PC or an SD card) , it still won't work.
Damned walled gardens. the note 12 is a decent tablet otherwise for its price range.
:Edit: another thread on XDA reports a few new things...
firstly, make sure of what version of Android you're using (under settings, about device, software), as above, 4.4 has Flash issues, 5.0 has lots of video issues, which is why Amazon may be rejecting it as well. Apparently people have it running on 5.01 and 5.02 and other android versions.
then, try this set of very specific (order is important) instructions.

I saw in a tread for a different device that the issue is very device-specific... some like the kindle-fire will play just fine, but others like the nexus9 and the note12 have myriad issues. So again, this is Amazon running some proprietary stuff cooked right in to the core of their app and their version of android for the kindle. most reliable solution I have seen listed is the above steps, and then make sure that when your tablet starts up, start Instant Video first to make sure it is at the front of any memory cues for usage.
