Hello,
I have the same problem than @curvaturegames
Initialy, my project was in Unity 2021.3.24 and URP 12.1.11
I tried to upgrade to Unity 2022.3.3 (as 2022.3.22 doesnt exist in archives, BTW, on this version, minimal URP version is 14.0.8, so i think you are talking about 2021)
But i cant get passthrough underlay working.even in the Toolkit sample (overlay works on both version)
Are you working on focus 3 ?
