Hey @Arnav_alpha! We definitely want for you to be able to redeem your copy of Beat Saber! We're here to help.
If you just activated your new Quest 2 on your account for the first time, you should get an email that has a link to follow to redeem your copy of Beat Saber to your account. If you don't see it in your inbox, make sure you check your junk/spam folders too. Once you do that, you should be able to install it on your headset!
If you can't find the email or have any trouble redeeming it, go ahead and send us a private message so we can get some account info and look into this for you!
