Since upgrading to IOS 8.1 the auto backup is not working. It pops up to remind me daily as usual but when I click the backup it does nothing.
When I then go into SetUp->Database->Online Backup and restore it confirms there is no recent backup.
I have to press the backup button (top right) to manually force it and it appears not to work sometimes.
I also have the "entry on edit screen" all the time so waiting for Apple to publish On-Cores Fix for this but that is annoying, this one is a risk in case I lose valuable billing data!
