My 11 year old is taking up all our icloud storage even though she doesn't need any of her videos backed up.
I enabled family sharing so that my wife and I can share the icloud space to back up our data. However, I set up my 11 year old daughter's iPad with a family account so that I can control her usage. But she is part of the family sharing and takes up most of the storage to the point where it is always full. She says she doesn't need any of it backed up, but family sharing doesn't allow me to remove anyone under 13 from family sharing. Is there a solution to free up the icloud storage space. She takes up over 75% of the space.
