Hi there, I have an iPad Air 128GB, and in the past couple of weeks I have started to get a message advising I am almost out of storage. I have checked in Settings and it looks like I am using 106GB, however when I check in Manage Storage and manually add up the storage used by all of my Apps, it is only around 33GB. I am at a real loss as to what could possibly be using 70GB that I'm not aware of. Can anyone help or advise please? Thanks
