Hi @Jp241 and welcome to the forum. I have had this problem from time to time with my puck and a reboot always resolves it for me but if in your case it doesn't then try paring your remote to your Glass TV again.
To reboot go to Settings > System Management > Resets & Updates > Restart device (do not do a factory reset). It takes about 3 minutes to completely reboot. You will have a blank screen for a couple of minutes before the Sky logo appears so don’t worry when this happens as you start the process.
To pair your remote again press 1 and 3 together for three seconds and follow the on-screen instructions.
