Welcome to the Roku Community, @mg4499!
Thank you for reaching out and sharing your concerns regarding your Roku device. We value your input and would be grateful if you could provide us with additional details about the issue you’re facing. Specifically, could you clarify if you’re interested in using the Spectrum RC-122 remote with your Roku Ultra? If that’s the case, we'd like to inform you that while universal remotes can be used with Roku TVs, they unfortunately do not work with Roku streaming devices such as the Roku Ultra.
I hope I have addressed your question appropriately. If the above does not fix your issue, reply to this message, and we will gladly follow up.
Thanks,
Jharra
