I agree, but this forum is still your best hope. You need to give us the model number of your Roku. It should be written on it somewhere. Is it a stick that plugs directly into an HDMI port on your TV or a little box that connects with an HDMI cable?
One is a 3800RW...it’s the stick. The other is older and is the box. I’d have to check the model number. It was an accident setting both of them up on the app. I didn’t realize it would do it automatically. Also a bunch of **bleep** lol.
Make certain you use the right remote with each Roku, depending on the model. The stick models MUST use a WiFi-direct remote. Non-stick models support IR, and many also support WiFi-direct, even if they don't come with out out-of-the-box. You can also post the model numbers of the remotes. It is probably in the battery compartment, and typically starts with "RC".
