Apple is ending the iTunes Allowance feature, which let parents create a limited spending option for their kids:
After April 13, 2016, you will no longer be able to create a new iTunes Allowance. All existing allowances will cancel May 25, 2016.
After May 25, any unused allowance credit will remain in the recipient’s account until it’s used.
For a replacement, Apple suggests using Family Sharing. Maybe that means the company will finally fix some of the myriad glitches and problems with that system. Or maybe that is wishful thinking.
