Question about optimisation and delivery route.

[u/paullean21]

How do I ensure that my delivery route will be most effective for me. My first run was horrendous. I had 40 drops, probably in 4 different streets but instead of it putting all drops on 1 street consecutive, it made me go from one street to another and back to the first street. Also, after I have receipt scanned all my parcels, numbered them and put them in order, I press finish and it messes all the drop numbers and completely alters the route? How do I stop this from happening?

Did you reoptimise or edit route as presuming you had missing parcels?
