Oculus Splash screen image no longer shows on Quest.
Unable to reproduce on PC (If you package a project without 'Start in VR' enabled you will be able to see splash until you enable HMD)
Confirmed that SplashDescs is updated in both versions DefaultEngine.ini
In Project Settings -> OculusVR add an element to Splash Descs and set a texture (AICON - Green used in my test)
Launch on Device (Quest)
In 4.22 the texture is visible when opening app, in 4.23+ you just see the 3 dots.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-84307 in the post.
