Unable to Access Zoho email via Microsoft Edge

I am unable to get into my Zoho email via Microsoft Edge today.   I seem to be able to get in via Firefox however, but I think I was told by Zoho over a  year ago that Zoho isn't compatible with Firefox.  Has this changed?  I've also just sent two test emails via Firefox, but the emails do not seem to be going out.
