Apple has released a new update within a week of rolling out the iOS 10.1 to all eligible iPhones, iPads and iPods.
The new iOS 10.1.1 firmware is 70MB in size. Though it may sound like a minor update, it actually fixes a critical bug found in iOS 10.1. Many users noticed soon after upgrading their devices to the iOS 10.1 that information in their Health app got erased without warning.
Initial reports suggested that the health data might have been completely erased from the devices. Now, it has come to light that the data was just hidden in the background and by updating to the new iOS 10.1.1, users will be able get access to that information.
