I cannot find how to quit Nextcloud 3.0.1 so it doesn’t show in the menu bar. I had to go to the Activity Monitor to manually kill it. I clicked everywhere (I think) in the interface, but can’t find the Quit button. Thanks to anyone for pointing out where I can find it.
Select the dropdown menu next to your account (top left) and there you can exit.
Have no Mac here, so no screenshot for you at the moment
Took myself also some minutes to find it.

Same here on MacOS Mojave.
