I need help, even t in my account i can't buy individually because my family sharing keeps asking for Credit Card of the manager! I want to rent movie worth $4.99, and i have $7.39 but it still asks me for Credit Card security code from manager!
This would occur if the credit card the family manager set up was declined the last time it was tried, and/or there is a balance owing to Apple for a prior purchase that did not go through. In any case, the family manager will have to resolve the issue.
