Bad news, Apple Watch owners. Apple has announced it will not be releasing the latest version of its watchOS 2 after finding a bug in the new software. The free upgrade to watchOS 2 was planned to be released alongside the new iOS 9 on 16 September but just hours before Watch wearers were expecting to see the notification update pop up on their devices, it was postponed to a yet-to-be-announced later date.

The reported reason behind the decision to pull the update is due to a significant battery drain from the new software, which was discovered by app developers who have been testing beta versions of the watchOS 2.

In a statement, Apple said: "We have discovered a bug in development of watchOS 2 that is taking a bit longer to fix than we expected. We will not release watchOS 2 today but will shortly."

The software, which was shown off at Apple's "monster" event earlier in September, will bring native third-party apps so developers can make use of features such as the Digital Crown and heart rate monitor. Other features include new faces, a time travel feature that allows you to see your schedule in the future and past, as well as nightstand mode and Transit directions.

IBTimes UK will keep you updated on further developments and when we might expect Apple to roll-out the new update.
