Troubles paying lunch balances online?

Good Afternoon! Some parents are having issues with Paypal not letting them pay on their child's lunch account. I have contacted SIS and there is not an issue on our end. I then contacted Paypal and they said to advise all parents having issues paying online for lunch balances to call Paypal directly because they will have to take a look at it from the parent's account. Apparently, they cannot access it from our school account. Thanks!
