Thanks for the post.
Can you please specify the issue you are experiencing? When removing a channel, did you make sure to restart the device before adding the channel back again, specifically in that order?
If you are still unable to resolve the issue, can you please provide us the following information:
-Roku device model, serial number, device ID, and software OS/version (these can all be found in Settings > System > About)
-does this issue occur on a specific channel? if so, what channel and what version/build is the channel (this can be found be selecting the channel on the Home screen and pressing the * button)
-tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times)
-steps to reproduce the issue you are seeing
Once we have this information, we will be able to assist you further.
