I was playing with termux and apparently answered a debconf prompt wrong and now a bunch of cpan modules are being installed on my phone. The future is strange.
My daughter has an Xbox / Microsoft account. The Xbox side is definitely a child account - can't access any settings there. But the Microsoft side seems like it's an adult account. And I certainly can't find out which Xbox account (I seem to have a few, somehow) is in change of her Xbox account. I guess we're pretty close to "delete all the accounts and start again" territory
