I wish to update my Apple Watch Series 10 to watchOS 27. As I found on the official page, it is supported on my device. And my iPhone is already updated to iOS 27. However, Watch apps on my iPhone fails with the "Unable to Check for Update" issue, screenshot below.
How it's unable to check? I think checking for update is something very simple and lightweight: pull the version from Apple server, compare to my watch version, that it. Why do my watch struggle?
Anyway, I'm here not to understand the reason deeply, but to solve the issue. Did you encounter it? How did you solve it? What would you suggest?
