Oculus branch 4.22 - it has the latest OculusVR plugin (version 1.39) which seems to work best for Quest.
However the Oculus 4.23 branch has the same issues as the Epic 4.23 Previews so worried no one is noticing / fixing it. Also annoying that Epic’s 4.23 is currently only bundled with OculusVR plugin version 1.36 as opposed to the latest 1.39 version (which contains lots of Vulkan fixes and improvements)
