How are pre-schoolers even able to pay? My 10 year occasionally begs me for micro transactions in these rando games she installs even though she knows it's useless. She can't actually buy anything herself because 1. kids don't have credit cards and 2. I just don't give her mine.
Maybe I am guessing too much here, but I got kids, and one iPad, and my kids use the iPad.
The fact that there is no multiple accounts set up for iPad is on Apple and their greed so that we have to buy multiple devices. Imagine doing the same with a Mac.
Some parents don't use a separate profile for kids and have their app store purchase settings set to the low friction mode that lets you click and buy on the main payment method without any additional confirmation when the phone is unlocked.
