Noteworthy among them is the display of blood glucose data, which has been temporarily disabled for the Health App as Apple is working to add compatibility with the devices that display the metric in mmol/L (millimoles per liter), reports AppleInsider.

Currently, the Health App does not offer the ability to manually enter and view blood glucose values using that particular unit of measurement. Apple will prevent this confusion via the software update. Besides, a fix is in work with the third-party developers can access the APIs.

iOS 8.1.1 is compatible with iPhone 4S, iPhone 5, iPhone 5c, iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air 2, iPad mini 3, iPad 2, iPad 3, iPad 4, iPad Air, iPad mini, iPad mini with Retina display and iPod touch 5g.
