Some UI Functions Do Not Work For Certain Versions of Internet Explorer

A few UI functionalities do not work on the Internet Explorer 11.420 and Internet Explorer 11.447 versions of the browser. Why?

Currently, in the TIBCO Product and Service Catalog user interface, functionality like the menu to modify a record or to remove a record is not displayed. Additionally, on the Browse and Search screen, a product search does not fetch any records. Both issues occur if TIBCO Product and Service Catalog UI is accessed using the Internet Explorer browser versions 11.420 or 11.447. The issues do not occur if TIBCO Product and Service Catalog UI is accessed using the Internet Explorer browser version 11.662. We recommend you use Internet Explorer 11.672, Google Chrome, or Mozilla Firefox.
