Deanna4 Your remote buttons may be getting stuck or are worn out. Also, IR Signals from the remote can be negatively affected be a light or sunlight glares. If it is happening on two devices and only on the Roku channel then the remote might not be the issue, but it may be worth it to try a new remote. You can get them on Amazon for around $10 and they work out of the box, no need to pair with your TV.
Other things to try:
- Go to Settings > System > Software Update and check for an update.
or
- Uninstall the Roku Channel, reboot, and install it again.
Good luck.
