Beta Tab & Passthrough Toggle Missing in Meta Horizon Link (v83) - Wired Link

Hi everyone,

I’m seeking help regarding a change in the Meta Horizon Link software (Windows) that has disrupted my MR development workflow.

The Issue: Previously, I used the "Enable Passthrough" toggle within the Settings to test MR features in Unity. When enabled, I could see the passthrough background in my Quest 3 while in Unity Play mode.

However, in the current version (83.0.0.330.349), the "Beta" tab has completely disappeared from the Settings menu, and I can no longer find the Passthrough toggle anywhere else. Consequently, passthrough is not functioning when I press Play in Unity.

My Setup & What I've Tried:

• Meta Horizon Link Version: 83.0.0.330.349
• Connection: Wired Link (USB-C)
• Headset: Meta Quest 3
• OpenXR Runtime: I have already confirmed that "Meta Quest Link" is set as the active OpenXR Runtime in the General tab.
• Development Tool: Unity

Questions:

1. Is the "Beta" tab being deprecated or moved in version 83?
2. Where can I now find the setting to enable Passthrough over Link for Unity development?
3. Is this a known UI bug in this specific version, and is there a workaround to force-enable passthrough?

Testing MR functionality is critical for my project, so any guidance would be much appreciated.

Thank you!
