Thanks for your elaborate answer. This confirms my suspicion regarding “support” from Meta. So I sold my Rift S today and am on board for a Quest 2. Sad that this is the only real solution, since I was happy with my Rift S as is.
Quest 2 is pretty great actually IMHO.
I use it with Virtual Desktop, and a 5GHz WiFi. Works pretty well for me. The quality isn't perfect, but it's far superior to that of the first generations of VR! Also, having a wireless VR headset just beats all the others because it's wireless. I don't like the wired ones. Anyway that's my opinion of the matter.
