I hope I can get some help with this problem. Applecare has been no help whatsoever after hours of conversation.. I have (2) iPad Airs and (2) iPhones 6. All running iOS 9.0.2. All connected to iCloud with the same account. The same problem with all devices since I upgraded to iOS 9. They are all 16 GB devices, iPads worked fine for almost 2 years, iPhones for 1 year. Apps and supporting data have been managed so that there is usually 4-5 GB available free storage. Every day or two (randomly on each device) I get a warning of no available storage. I go into Settings/General/About and the available storage is shown to be 0 bytes. I connect the device to iTunes, and see that all the free space, more than 5 GB, has been taken up by “other”. It wasn't there yesterday. Again, this isn’t a gradual thing. It happens within a day, sometimes even after the device has been unused for just a few hours. Sometime a re-boot will clear some space, other times I have to do a backup and restore. Then in a day or two “other” fills up again. Any suggestions will be appreciated.
