After Apple unveiled its latest software updates at the Worldwide Developers Conference (WWDC), some tech fans are in for an unexpected disappointment.

Apple's watchOS 27 update is now available in developer beta. This year, the company has slashed the number of supported models in half.

Although watchOS 27 drops support for several older Apple Watch models, Apple has confirmed to 9to5Mac that one compatible model was mistakenly left out of its official list.
