A warm welcome here in the Roku Community, @Pamala.
We'd be more than happy to find you the best resolution possible.
If you want to revert back to default, you may sign out of the guest mode feature by navigating to your Home screen. Scroll and select Guest Mode Options, and select Sign out and Clear info. You can also log into our official Roku Website and disable the Guest Mode.
Let us know how it goes and we'll go from there. Hope this helps!
Best regards,
Carly
