When you complete a delivery on an own-vehicle delivery run, if this was completed early/late, Breww will recalculate the ETAs and drive times for the subsequent deliveries on this run. This ensures that if a driver gets behind (or ahead) of schedule, then the ETAs will be automatically updated to reflect the new times.

This feature only applies if you have our Advanced Deliveries addon on your account. This feature is enabled by default on all accounts (with the Advanced Deliveries addon), but if you don't want it enabled, you can switch it off (so ETAs are not recalculated) in Settings > Delivery settings.
