> but just yesterday I spent an extra 25 minutes going through the same roundabout 3 times

How big was this roundabout when it took 25 minutes doing 3 victory laps in a roundabout?

You might want to petition your local government to put the signs of the exits before the roundabout, together with exit signs inside of the roundabout, helps a lot to see what exit you should take.

Alternatively, try a different map viewer, both Google Maps and Waze handles roundabouts excellently with zero issues, Apple Maps might still be too new to be useful for daily use.
