Why am I getting a low disk space warning
My wife’s iPad Pro is giving her a “Low Disk Space Warning” when she opens the Nook app and her available space drops below 8Gb. If she doesn’t do anything, then her books are deleted from the Nook app. Is this an issue with the iPad, iOS or Nook app (maybe combination)? Does iOS 11 reserve space for running Apps or other operations? I have tried to find information related to this without success. Any help would be appreciated.
She’s really frustrated at having to upload her books every time they get deleted.
iPad Pro 12.9-inch Wi-Fi, iOS 11.1
