It appears that some people are talking about different behavior from what the OP was talking about. I experience a bug like what the OP described, namely that when initiating ff/rw, then stopping at that point I want to resume play, the app gets stuck in a loop whereby it plays for literally just one second, then a spinner appears and the timeline moves forward/back a few seconds, then plays for one second, then the spinner appears, and... rinse/repeat indefinitely.
I have to exit the show I'm watching to stop the bug, but if I try to ff/rw again, it happens again. I've done everything from the move-channel hack to a system restart, but nothing changes this bug. Latest version of prime video and of Roku. Something is definitely wrong.
Thanks for the post.
For more information about that channel's features and functionality, you'll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
Thanks,
Danny
For a problem that's been around for several years, this shows the limits of community support, since obviously no one from Amazon Prime is reading this, and no one from Roku is telling Amazon about it either.
I found this link in 30 seconds. Prime Video - Amazon Customer Service. Now you can let Amazon know about your problem.
