Roku remote automatically add an app

Sounds like those new rechargeable remotes are ghost-tapping and making the Roku think you’re trying to add a channel. I’ve seen that—it’s usually a pairing glitch, not Disney+ or Apple TV. First, unpair and re-pair the remotes: go to Settings → Remotes & devices → Remotes → Set up a new remote and run through it. Then power-cycle the Roku by unplugging it for about 30 seconds and plugging it back in. After it boots, check for updates in Settings → System → System update, and also look at the remote firmware under Remotes & devices. Finally, test with just one remote—put the other in another room or pull its battery for a bit—and see if the issue stops. If this only started with the new remotes, one of them is probably buggy or mispaired.
