Thanks for bringing this to our attention.
Does the issue you're experiencing only happens on a specific channel or across the channels on your Roku device? Please let us know as well how your Roku player is powered. Is it connected to the USB port at the back of your TV or to a wall outlet?
In some cases, the USB power provided by the TV is not sufficient to power the device. Even though your Roku device may appear to be working, running with insufficient power can lead to instability, crashing, and other unpredictable behavior.
We suggest using the included power cord and power adapter then plug your Roku into a working power outlet in the wall. Powering it through a power outlet in the wall has the additional advantage that your Roku player will not need to power up every time you turn on your TV.
Let us know if this works for you!
All the best,
