I'm currently using Microsoft Edge (Chromium) Version 100.0.1185.36, and trying to load into the ProConnect Online app redirects me to an error page:

Sorry, ProConnect Tax Online doesn't support your browser.

Try using a more up-to-date browser from the list below:

• Google Chrome (Version 60 or higher)
• Mozilla Firefox (Version 50 or higher)
• Microsoft Internet Explorer (Version 12 or higher)
• Microsoft Edge (Version 49 or higher)

Thanks for upgrading and keeping the web moving forward!

As you can see from the UA string, the browser exceeds the minimum requirements for using ProConnect Online.
