I have a Quest 2 and I just updated it to test whether everything's still working correctly.
When I upgraded, it changed to using a Meta account instead of a Facebook account or an old Oculus account.
After getting everything updated with regards to the account, I found that Oculus Link (now called Quest Link) was not appearing in the Quick Settings in the headset anymore.
To enable Quest Link (via cable or Wi-Fi "air" link):
From within the headset, go to Quick Settings, then push the Settings button in the upper-right corner, then push the System button in the upper-left corner, and then press Quest Link in the list just below Keyboard. Enable the Quest Link toggle, and then either press the Launch Quest Link button there, or press the Quest Link button that now appears on Quick Settings after it is enabled. (See Use Quest Link with Meta Quest 2 or Meta Quest | Meta Store)
Once Quest Link was enabled and I was able to access the Oculus Rift content on my PC, then FlexSim's VR Mode worked as normal.
Does this help solve your problem or are you having some other issue connecting?
