The Avenza Map Store Settings page provides three options to users to in order to manage the Map Store, and as well as provide troubleshooting options.
Local Purchase History
This provides a detailed list of all purchases made on the local device. If map purchases are made while not logged in with an Avenza Map Store account, or if there is an error with a purchase, this is required when contacting Support in order to assist with locating the transactions details.
This can be used to point to a specific map server. Typically this is not required, and should be left blank in order to access the default server.
Reset Avenza Map Store Cache
This will reset the Map Store cache, thereby removing local purchase records. This is sometimes recommended to do if there are problems with the Map Store (e.g. making purchases, no prices showing up, etc.).
