Thanks for the post.
Can you please specify the issue you are experiencing? What Roku model device are you using? Have you already tried factory resetting your Roku device?
For clarification, if you are setting up your Roku device, the Roku mobile app will not be able to connect to your Roku device until the device is on the same wireless network as the mobile device.
With more detailed information, we will be able to assist you further.
Thanks,
Danny
