The Weather Complication Is Having…Complications
If you love checking the weather on your Apple Watch by looking at the complications, you might want to wait before updating to watchOS 10. Many users have reported that the Weather complication isn’t working properly anymore.
For instance, instead of looking at the weather from the watch face, the data appears blank. You can, however, still look at the data by opening the Weather app on your Watch, but it defeats the purpose of having a complication.
It was first believed that updating your Apple Watch to watchOS 10.0.2 fixed this issue, but a lot of users are still experiencing it; watchOS 10.1 is in public beta now and has reportedly fixed this problem on the Apple Watch Series 9 and Apple Watch Ultra 2 in the very first beta release, but it’s unclear whether it’s done anything for older models yet.
