I cannot see how to activate dark Mode for any of my Google Apps. My S9+ running Pie is setup for Night Mode. From what I've read, Google calendar should have a option for Dark Theme, but I can't find it.
I believe this is what it's being called in Android Q so that option may not be there until then. I have a Pixel 2 XL and don't have any dark options for the Google Calendar app, yet.
That setting for Dark Theme was not there when I first posted this. I'd read the tech blogs and saw that was where it was Supposed to be, but wasn't. I must have gotten a recent update that enabled this feature. Thanks.
