Fresh project (simple scene: “just falling cube with rigidbody”) when I press the button  “Play” starts in 3 seconds and this is perfect, but when I turn on Oculus  “XR Plug-in Management” it takes more than 20 seconds to start this super simple scene!!! How can I fix it???

      In case anyone needs it:

      I've found a fix for that pesky bug! The key is ensuring your Quest 3 and PC Meta Link App are on the same version number (currently "62").

      Here's the solution:

      1. Update your Meta Link App: Get the latest version, 62.0.0.235.346 (62.0.0.235.346).
      2. Update your Meta Quest 3: Grab the newest update, 62.0.0.247.343.563460087.

      After that, you should be back to smooth development in any Unity version!

      P.S. Stuck on Quest 3 version "60"? No worries! Join the Public Test Channel in the Meta Quest app on your phone. This lets you manually update to 62 using the Software Update option on your Quest 3.

      I think this is the 2nd worst bug I've ever encountered.

      For hours I been working on this "pre-play delay". Sadly, as a noob, my knowledge of the Profiler is somewhat naïve. I tried it, but failed to notice - ahh - never mind. You saved my life. How I ended up with 2 different versions is beyond me. And shouldn't be allowed if this is a typical result.

      To enrol in the Oculus Rift S and Rift Public Test Channel:

      1. Open the Oculus app on your PC.
      2. Select Settings in the left menu, then select the Beta tab.
      3. Select the toggle next to Public Test Channel to enrol.

      It does various updating, but basically time to actual play went from 22 seconds to less than 1. Unity owes you!

      Thank you, thank you, thank you!
