Prime and Netflix app goes back to the home screen
I am having the same issue. My Prime works on my DS television but I got a new TV for the bedroom US and when I select the Prime app it starts to load then goes back to the home screen. It does the same thing with my Netflix app.
Thanks for letting us know about the issue you're experiencing.
In some cases, removing the channel and then re-installing it may help. To ensure the process is successful, follow the steps below making sure you restart your Roku device before adding the channel again.
Remove the channel: Highlight the channel tile on your home screen and press the Star button to open the options menu. Select Remove channel and confirm.
Restart your Roku device: Restart the device from the settings menu. Go to Settings > System > System restart > Restart.
Re-install the channel: After your Roku device restarts, visit the Roku Channel Store and add the channel again.
Re: Prime and Netflix app goes back to the home screen
I did all of the recommendations and still not working, the rental starts playing, then goes back to the home screen, I pick Prime again, it starts up with no issue and then closes down, tried forwarding through and it worked for about 15 seconds and then again returns to home screen
If you are still unable to play videos from one channel after attempting the suggestions above, videos from other channels play fine, contact the channel provider's customer support team to report the issue and get help. Channels on Roku are maintained by the channel developer themselves. In this case, there's likely an issue within that specific channel that needs to be addressed with an update from the channel developer.
