When using a Meta Quest device with ArborXR, you need a verified Meta account in an Oculus Developer Organization. This allows you to enable Developer Mode on each Meta account that you log into each device.
If you can't see the Developer Mode toggle under Menu > Devices > Select your device > Developer Mode (see example below) in the Meta Quest mobile app, try these troubleshooting steps:
Force close the Meta Quest mobile app
Enable text message two-factor authentication
Log into your Meta account's Password and Security section then go to Two-factor authentication > Text messages.
Complete the verification process.
