There's no set wait. When your account opens depends on how much delivery work businesses are posting near you, and that changes from week to week.
Activation is automatic and follows that demand. There's no place in line to move up, so asking us to speed it up doesn't change the timing.
We'll contact you once your account is ready. It arrives as a text message or a push notification, so keep notifications turned on and watch your texts.
Two things are worth doing while you wait. Keep the address on your profile current, because that's what places you in a delivery area. Finish the rest of your profile, so nothing holds you up on the day your account opens.
