Android phone Google calendar app help - add location

Marshmallow 6.0

How do you add a location to an event such as an appointment? When I tap “add location,” it goes to another screen with a field and a back arrow. When I enter a location into the field, then tap the back arrow, it goes back to the screen where I enter the time and date, but doesn’t put anything into the location.

Never mind. I figured it out. Mods, please lock.

Sorry, I don’t have a 6.0 system. On my phone (Android 8), when I tap on “location” and start filling out that field, it starts giving me options based on partial input. Once I select one, a “Save” button appears.

Yes, as noted, I did figure that out.
