Bummer. I was really looking forward to watchOS 2 launching today. It includes new complications, new watch faces, a bedside mode and so much more. But it won’t launch today, Apple said.

Apparently the company ran into a last minute bug that it discovered as it was preparing for the mass rollout. It’s always good to catch these things before millions of people discover it, but it’s also a huge bummer that Apple is missing a promised deadline. “We have discovered a bug in development of watchOS 2 that is taking a bit longer to fix than we expected,” Apple told TechCrunch on Wednesday. “We will not release watchOS 2 today but will shortly.

At least we’ll still get iOS 9 today. We hope.
