Hi there,
I'm new to VR development and very excited to get started with the Quest.
Trouble is, I can't seem to build and run my project, I get the following errors:

When I click "Use Highest Installed"

When I try to update:

However as far as I can see in the Build Settings, the SDK is actually being detected, and the Oculus Quest is recognised.

It might be worth noting that I had a similar problem before where the android sdk wasn't being detected at all which was "fixed" by a reinstall of unity.
If anyone can help I'd massively appreciate your help!
Cheers,
Pat
