Explanation
According to the Salesforce Help article on Routes and Schedule Settings in Maps2, you can enter your travel plans via the Maps Advanced Route tab to let the optimization engine know when and where you will be traveling. This will help you get more accurate routes that accommodate your travel plan.

Explanation
Because Salesforce Maps is an installed package, its data and configurations cannot be moved via change sets.
Change sets can only move metadata components between orgs, not data records or custom settings.
Therefore, the Maps Administrator should consider recreating the Salesforce Maps data and configurations by hand in the destination org, or using a third-party tool or API to automate the process. This is explained in the Salesforce Maps Apex Developer Guide.

Explanation
The user should tap the refresh button located at the bottom of the map to display additional accounts. This button reloads the marker layer data based on the current map view and filters. This is useful when the user changes the map view by zooming in or out, or panning across the map. This is explained in the Interact with Salesforce Maps on Mobile document.

Explanation
Automatic route re-optimization is a feature that requires purchasing Salesforce Maps Advanced. This feature allows users to automatically adjust their routes based on real-time traffic conditions, customer availability, and other factors. This feature can help users save time, fuel, and money by finding the most efficient routes for their visits. This feature is explained in the Salesforce Maps Products document.

Explanation
The Admin should enable "Allow Route/Schedule Sharing" to ensure all Maps Users can see each other's Routes and Schedules. This setting allows users to share their Routes and Schedules with other users in their org, and also view the Routes and Schedules of other users who have shared them. This setting can be found in the Routes and Schedule settings within Maps Configuration. This is explained in the Routes and Schedule Settings in Maps document.
