When I edit the channels on one Roku device, it is editing them on the other two as well.
We own three Roku devices. Two of them we have had for over a year, but I just bought one for my son yesterday. He is 4 so I don't want him to have access to all the channels we have, but when I deleted the channels, it also deleted the channels from our other two devices. When I added the channels back to my daughter's device, it added them to my son's as well. Is there a way to fix this?
Let me add to what @renojim and @Strega said. But first, they are absolutely correct in that for Roku devices to have different app lineups, they must be on different accounts.
One issue you may encounter is if you have subscribed to a service via Roku Pay. That can't be shared with other accounts, so if, for example, you subscribed to Netflix via Roku Pay, only your Roku would be able to use that subscription. You son's couldn't and your daughter's couldn't.
But, to get around this, the solution is to not subscribe via Roku Pay. Instead, subscribe directly to Netflix (in this example) and use those credentials on each of the devices. That lets you have separate app lineups and still share the subscriptions.
Oh, and you may want to consider putting a PIN on each of the accounts to keep them from adding apps, since you're looking to control that. One PIN option is for purchases only, and you'll certainly want that. The other is for adding apps, and that may be something that will fit with your intent.
