Meta quest pro left controller

So I just got this new headset about two weeks ago. I’m not very techy but I’ve done everything I could to try and fix my controllers. My left one is deciding not to pair or even connect, even though it’s fully charged. The light will turn on, I’ll feel the buzz when trying to pair, but it still decides not to pair or show up. I’ve looked at several discussions and tried researching online but nothing helps or tells me what to do. I’ve held down the buttons, restarted the headset, no luck.
