I'll try that next time (if there IS a next time). Silly me, I looked under 'A' for Amazon.
So let me tell you another weird thing. So I said it was up at 1:45. Well, that was on this computer checking the Amazon website. So I clicked "Your Watchlist" so it would be first under "My Videos" on the Fire 4K Stick (most recent/top-of-the-line) version, turned off the computer and went into the living room to watch it on the big screen.
Lord almighty, it was not on my Fire 4K Stick. I clicked sync my account and then restart and when it came back up, it STILL wasn't there.
So I start up my Fire Tablet I keep with my remotes, go to the Amazon Prime App and, by jingo, it was there. Still not on the mighty Fire 4K Stick, though. Luckily, there was a selection on the tablet that said "Play here or On TV?" I pressed "On TV" and it was finally playing on the big TV.
As of now (5:17), it is STILL not on the Fire Stick under the HBO Channel and will show up only under "Recently Played".
Weird, huh?
BTW, great movie. Will cancel HBO soon.
