quest 3 newbie dev connect issue mistakes

Hi!

So, day 1 and the Mrs has setup the quest, I've also got my Dev account but as a visitor / guest / additional profile. I'm trying to connect to mqdh but it won't connect. The instructions say "make sure you are logged in with the same account" and mine is the active profile.

Do I need to be the admin user? (I.e. wipe and restart)?

Bonus question, if we wipe and restart, will the game sharing only work from the admin account and any games my wife has already bought only work under her profile?
