I have been trying to update my apps but it said there is a problem with a recent purchase. I cancelled my card because there was high amounts charged to my card that I didn't make. I believe it was my kids. Is there any way to update them.
You need a valid form of payment on your account to update apps or download even free apps. If it's your kids just don't give them your Apple ID password. If it isn't your kids cancel your card NOW and get a replacement.
