The keyboard when logging in is on button up when type. Both on quest and PC.
This should be changed so it's registering the keyboard press when you press the trigger down rather than up. Right now it is registering the press when you let go of the trigger.
We got a fix for this to the in game keyboard a while back. So would be nice if the keyboards was consistent. (Might be time to give it the visual overhaul at the same time 😏)
