It does, but it’s also slow.
For Apple to change that, it means that there must be data showing that people changing their watch faces by mistake happens more frequently than people changing Watch faces on purpose.
This would be an interesting observation, if the case.
The question is then why people who change between Watch faces by accident don’t remove the rest of the watch faces and only have one so that they can’t accidentally swipe and instead Apple has to take away functionality that some might be using. As I said, it sounds as if they have strong indication people don’t use more than one watch face. Curious why is that.
