My games start where I am looking behind myself. So, beatsaber starts looking the oposite directions as the menus. Could it be a problem with the software?
Hold/Press the Oculus home button (on the right controller). This will bring up an interface that has a circular...tool bar in front of you. On the far right side of this, if you point the cursor at it, there is an option to Reset View (its near the speaker and microphone volume controls). Follow the instructions and it will make where ever you are currently facing be forward.
