MapifyPro uses an API key system that should allow you to update in your wp-admin just like any other plugin. However sometimes there comes a case where you need to update manually. To do so, follow these steps:
1. Download the latest copy of MapifyPro from your account area.
2. Deactivate and delete your current version of MapifyPro in the wp-admin's Plugins panel. DON'T WORRY. All map settings and locations will remain intact if you do it this way. However you don't want to delete it via FTP unless you don't mind losing your current map/location data.
3. Upload the latest version of MapifyPro in the plugins section as you did with your original copy. Activate as you would any other plugin.
4. Activate the API Key.
That's it! You're all set and have successfully updated your copy of MapifyPro.
