Currently, Landboss uses Silverlight for the mapping control, but support for that technology has been dropped. We are currently working on replacing the mapping control with a version that will work in all major browsers, but in the meantime, you can take advantage of IE Mode in Microsoft Edge to access the map in Landboss even after Microsoft officially retires Internet Explorer.
To learn how to enable and use IE Mode, which will be supported until at least 2029, please refer to our help article.
