Last night, Micro Soft Edge was downloaded to my computer and since that point we get a blank sign on window when trying to log into Pro Series 2019.   2018 works, but not 2019.

Spent over an hour on the phone with Customer Support trying everything, but still doesn't work.  After the call, I changed the default browser back to Internet Explorer 11 and that didn't help.

HELP!!  Has anyone else had this problem and can provide some advice?
