Are kids who are added as participants (authorized users) to Apple Card and in the 13-18 age bracket automatically reported to the major credit bureaus? All I can find is that if an applicant turns 18 they can opt to be reported or not, but what happens for kids in the 13-18 age bracket? Are they automatically being reported too? Does anyone know? None of the Apple's support articles touch on that subject for some reasons as far as I can tell.
