Did you add the Shield from our IR library or pair the remote via Bluetooth? Bluetooth is the recommended way.

Sorry for the inconvenience! U3 does not currently support the function of hiding devices. We have already forwarded your request to our R&D department, and this feature will be added in a future update.

Sorry, the video is necessary for a possible replacement process if you have a defect unit.

Please make sure precise location access has been granted to the App. Also, please re-install the App and try again.

Thanks for your feedback! We have passed along your suggestion to our R&D team and will take it into consideration in future updates.

Could you take a video next time the remote freeze and send it to service@sofabaton.com? Our support team will follow up on this issue.

Please send us the exact model of your TV to service@sofabaton.com. A picture of the nameplate would be useful.

Please add the Xfinity by IR. Please note that the IR receiver on Xfinity is rather weak and has a really limited receiving angle. We suggest sticking the IR blaster that comes with the box onto the IR receiving area on your Xfinity. Here's an article from Xfinity for your reference: https://www.xfinity.com/support/articles/using-your-remote-control-with-an-ir-extender

Please make sure the remote has been updated to V3 firmware, then please factory reset the remote on our App, update the App to the latest version and set up devices and activities again.
