Sometimes my remote (#Black streaming stick model 3800) gets stuck on the introductory screen.
Once I resolve that issue, I go to the channel I want, and it gets stuck on the channel.
Then, I cannot even switch from ATT NOW to Pandora or Netflix etc. Nor can I adjust the volume.
Thanks for the inquiry.
We would recommend taking a look at the troubleshooting steps offered on our Support page here: How do I resolve problems with my Roku® enhanced "point-anywhere" remote?
