Hi Csalzman,
A warm welcome to the Roku Community!
We understand your concern about the ads you see on the Roku device and are sorry for the inconvenience this has caused you.
Please be aware that while we can't please everyone with the displayed ads, we do strive to avoid offensive images and other things that Roku users might disagree with.
Your Roku device's home page ads are usually targeted based on your viewing history and preferences. However, the ads may sometimes be inappropriate or too scary for children.
Your preferences are important. For more detailed information on the steps provided by AvsGunnar, visit our Support article to learn more about hiding an ad.
Remember that this will only apply to the ad on the home screen. Some third-party channels may also have advertisements that are not appropriate for children. In these cases, you may want to restrict access to those channels or monitor your child's viewing closely.
Don't hesitate to let us know if you have any questions or additional feedback.
All the best,
Chel
