Hi @NeedSupport007,
Thanks for raising this concern, and welcome to the Roku Community!
Please be advised that you cannot watch or stream channels or movies on the Roku mobile app. However, the Roku mobile app is a free application for iOS and Android devices that turns your mobile device into a control center for your Roku streaming device. You can also use the Roku mobile app to manage the apps on your Roku streaming device: Access the Store to add and remove apps.
We hope this helps.
Best regards,
John
