THE MISSING CIRCLE COLOR CONTROL
If you are one of the users missing the Ambient Clock outline color setting, GOOD NEWS: it is coming back!
You can again control the color of the line around the ambient mode clock bubble independently from the active background color. This include of course making it disappear via the transparency scale.
Currently in beta (I don’t want to annoy users with too frequent updates) but if you need this setting, you can easily update.
