I mean she has had the roku device for over 2 months now and it just now started happening? Seems really weird. I'm gonna let her borrow my firestick and if that stops the ad's I'm just gonna toss the roku device and get her a fire stick because its playing over top of her shows. It's absolutely ridiculous she has to sit and watch two, two minute ads like shes being forced to. Again this has nothing to do with commercials, she still forced to watch the normal commercials which is typical with TV. But when the Roku Device is forcing ad's on top of it, it's a bit much.
Are you actually wanting help? I'm suspicious that you aren't. You were asked what Roku you had, and haven't answered. The folks here know how to help, and they know what information is useful in getting you that help. If you won't answer the questions others have, then you aren't serious about getting a solution. You might want to answer the question about what Roku device you have. You might want to include the software version. If you're actually are wanting help, that is.
