Users may notice a popup box that says, "Symantec by Broadcom Checking content... Your organization is checking to see if this content is sensitive." after uploading files in Microsoft Edge browser. Can this box is suppressed so users no longer see it?
DLP 25.1 and later
No, there is no way to suppress the "Checking content..." popup box. Microsoft chose to make it explicit to the end user because that is also a point of hand-off between the native user experience coming from Edge and the 3rd party user expeirence that may show up from the local DLP service provider which is Symantec DLP.
