Why can't I use MS Edge?

I have been unable to log into Quicken Community since last Friday. Every time I try to log in, when I get to the point of entering my credentials on the community.quicken.com website it goes to a completely blank page. The URL is: https://signin.quicken.com/signin/signup?response_type=code&client_id=quicken_estore&redirect_uri=https%3A//www.quicken.com/qam-callback

I use Microsoft Edge. I have used MS Edge with Quicken for MANY YEARS. I just tried Chrome, just in case [Removed - Rant/Speculation]
