The iOS 8.0.1 update is no longer available after multiple users earlier reported serious issues with the new version of the operating system, one that was expected to fix a glitch with the highly anticipated HealthKit apps.
Apple confirmed to Re/code that the company is investigating the issue and has pulled the update.
Many users on Twitter said they lost cellular signal, data service and Touch ID capability after updating to iOS 8.0.1. However, those with the iPhone 5 said they had no issues, and both MacRumors and TechCrunch reported that only the 6 and 6 Plus have had update problems.
Despite playing a large role in the September 9 media event, the HealthKit apps were delayed in the first version of iOS 8 launched last week.
