How do I reorder or optimise my routes in deliveries?

To reorder or optimize your routes, you can press the cog button at the very top of the deliveries list, make sure that you are on the deliveries screen, and scroll to the top of the page to see the icon.

Also, note that the "Optimise Route" feature has a limitation and will only sort your deliveries if you have fewer than 24 entries. This limitation is present because any more than 24 addresses are too complex to process and cannot be processed in a reasonable amount of time or will not be reliable in accuracy.
