It was working fine this morning, then went to watch a show on Disney+, but the app was glitchy, and lagging really bad, so I went back to home to see about an update, which took a couple minutes to do so, but once back on the home screen, the remote no longer responds. I changed out the batteries, with no luck, I can use the remote app on my phone, so I know it's the remote itself, I also unplugged roku, and plugged it back in. What else should I try?
