I'm trying to help someone who is an iPhone convert over to Lumia 920 - basically what happened was she setup a new live account at the AT&T store on the phone, and accidently did a birthday of 10/16/2012 not 10/16/1980 so the phone automatically went into My Family mode and won't allow any apps to be downloaded. We've tried to log in to live.com and change the birthdate but it wont let you. We've called AT&T who then called Nokia, but nobody knows.
Basically it's giving an error of "My Family setup needed - my family must be setup before you can buy this item. Ask your parent to setup My Family settings on windowsphone.com" when you download an app.
Does anyone know how to change the birthdate on the live.com account and also remove this My Family feature? It's a cool feature, it's just that there is no way to turn it off.
