Create a much softer and more comfortable Facial Interface
Now, I don't know what you changed when going from the Oculus Rift Facial Interface (original) to the Quest Facial Interface, but it's just an order of magnitude more uncomfortable to wear the Quest headset for any length of time because of how hard it feels on my face.
So, with both the included Facial Interface and replacement ones (assuming those are the same design), can you somehow figure out a design that is actually comfortable again, like the original Rift was, please.
Comfort, especially that regarding the headset pushing hard against the face, is one of the important things to nail here, especially for a device we're expected to wear for hours at a time (which I simply couldn't do with the Quest as is). I hope you do much better in this regard with Quest going forward.
