Apple will soon issue a software update that will temporarily remove the ability to track blood glucose levels in iOS 8's Health app following reports from users in the United Kingdom and Australia that the software is incompatible with standard measurements in these countries, Cnet reported Wednesday evening.
Existing blood glucose data won't be deleted from users' devices, said Apple in a support document detailing the issue. “Third-party apps will continue to be able to support both units of measurement and can continue to use HealthKit APIs to store blood glucose data,” reads the document.
A fix for the issue is being worked on and will be released in due time. Once the patch has been released, the previous blood sugar data will reappear in the Health app.
