Unity 2022.03.27 using URP 14.0.11 breaks the mirrors and portals when published to Quest. (it looks fine in the editor)
Currently investigating but it looks to be a hard one to fix
Will send a bug report to Unity.
[EDIT: a bug in URP causes some issues but this is easily fixed with a small edit in the URP source code, more info here: XRPass.GetViewport() Exceptions in Editor ]
