When I flatten the shape rounding corners for the "inner edges" (don't know what to call them) is greyed out:
In Illustrator however this is only a matter of a few clicks:
Here a better look at the desired outcome:
There surely is a way to do that in sketch, I figure. I'd be very thankful if someone could teach me how :)
