I tried scheduling exam for MD-100 and I get this error message in every browser I've used such as I9, Safari, Firefox, Chrome, and now Edge which is a MS product.
Please fix because I'm trying to take this exam and I can't go any further and Person Vue advised me to contact MS for troubleshooting.
