Xfinity has high requirements for the control Angle and distance, so it needs to be close to the box during the control, so that the box cannot be blocked to avoid affecting infrared signal reception

It is recommended that you hold down the Home button to wake up the Apple TV

This is the imperfection of our product. We will report your suggestions to the R&D department to see if there is a possibility of repair.

When using multiple remote controls at the same time (such as remote control 1, 2, 3), when you are programming remote control 3, you really need to turn off remote control 1 and 2 to prevent them from connecting with the APP.

Thank you for contacting us. U1 does not support Logitech's activity function. We are about to release a new remote control which will support activity function.
