We are experiencing the same issue. Removing the Netflix app and re-installing it as instructed did not solve. A few months ago Amazon Prime app was having same issue and setting it to not automatically show previews with movement from tile to tile solved problem. Though not ideal since we now have to manually view previews. Netflix app does not appear to have same setting. Also, have a Google Chromecast which does not suffer from these issues when watching Netflix or Amazon Prime. Seems to be something with Roku.
Hi jgp1236,
Thanks for posting here in the Roku Community!
We're glad to assist you with your problem on Netflix. If the issue persists on one channel after attempting the troubleshooting steps and videos from other channels play fine, we highly suggest that you contact the Netflix customer support team to report the issue and get help. The channel developers themselves maintain channels on Roku. In this case, an issue within that specific channel may need to be addressed with an update from them.
Kind regards,
Eunice
