Support was remove on Quest 2. I totally lost the internal debate over backwards compatibility.— John Carmack (@ID_AA_Carmack)
Facebook brought Go apps to the first Quest in late 2019, giving you a way to play and enjoy them even if you don’t have the the company’s standalone VR device. This June, Facebook discontinued the Go completely, since users prefer the Quest’s “six degrees of freedom movement” over the Go’s three degrees. It chose to focus on the Quest and the more expensive Rift going forward. While there are a bunch of games you can enjoy on the Quest 2, the only way you can now access any Go app or game you own is through the older devices.
