An Error Appears When Using the IE11 Version of Internet Explorer

Another issue with using the MapifyPro plugin on IE11 is that the Map does not display the Pinpoints and Pop-Ups. Refer to image below:

Recommended Browsers for MapifyPro

Since the map may not work properly as expected using the IE11, it is recommended to use another browser e.g. Microsoft Edge, Google Chrome, and Firefox may also be used as alternative browsers for the plugin.
