I have SideQuest working great on my main account. I've created a second (adult) Meta account for my kid, so we can play games together on our Quest 2 & 3. However, I'm having problems trying to add developer mode to that account so I can install SideQuest games.

I can't seem to link his account to the Meta Quest mobile app. Every time I try, it says to enter the 5 digit code, but no code displays on the Quest (I've tried with both the Quest 2 and Quest 3). So instead, I've tried installing Meta Quest Developer Hub, and using that. However, when I go to "Set Up New Device" in MQDH, it sees the Quest 2 but won't connect with it, and it doesn't see the Quest 3 at all. I'm doing this while logged into my kid's account on the device.

Any suggestions would be greatly appreciated. I'd like to eventually play QuestCraft and other games together, so getting SideQuest working on both accounts is important.
