We are seeing some issues with logging into the site using Microsoft Edge. Research on the internet indicates that the problem is with the browser not this web site.
The preferred solution is to switch to a better browser. Both Chrome and Firefox are very good browser and have shown no difficulty accessing the site. If you do wish to use Edge, clearing the cache and restarting the browser is the fix offered by Microsoft. Also updating Edge to the latest version is also supposed to solve the problem.
