Yes, of course I have. It shouldn't be necessary and it didn't work.
I paired and unpaired. That fixed the weather but not the sunrise/sunset. And it didn't, of course, fix the strap design flaw. Oh, and it took about 20 minutes.
I hear your pain. It always annoys me when stuff that should work doesn't. It makes me want to go and knock on their door and ask if they're having any problems with my thousand pounds...
I was confident the Apple watch wouldn't be all that. It's just a computer and, like the iPhone, would be filled with bugs, annoyances and dead-ends.
What's the issue with the sunrise/sunset thing?
