Just a heads-up from another Quest 2 user - if you're gentle, you can push the lenses in between the 3 predefined settings, and they will stay there. This helped me a lot, since my IPD is somewhere in between the middle and the wide setting.
Only 3 options is definitely a weird choice on Oculus' part (especially since the device apparently includes a potentiometer, so it actually acknowledges in-between settings!), but at least there's a workaround.
That's not a viable option for me as my IPD is not between settings but at the outer extreme of the widest setting (Quest 2 only goes as far as 68 mm while Quest 1 went to 72 mm which is close to my IPD).
It's still usable for games without any headaches, but I wouldn't use it for reading text or long gaming sessions.
