I am having issues with night mode on the modular ultra watch face. When it is on Auto and I tap to wake the watch, it comes on, dims down, and then comes back up to full brightness. Depending on the amount of ambient light, sometimes when it dims down, the night mode flashes and then the normal mode comes back up to full brightness. When I turn off night mode, it no longer dims when I tap to wake. I've submitted this info to Apple. I mentioned this in a thread here in the Apple Watch forum and got no responses, so it's probably just my watch having the issue. Other than that, I love the modular ultra watch face. It's one of the things that made me want the Ultra 2!
