AADSTS900561 error logging into Azure DevOps From Edge Browser

I am trying to use Edge to log in to Azure DevOps. This has worked in the past, but now when I try to log in I get:

AADSTS900561: The endpoint only accepts POST requests. Received a GET request.

I've read the links that come up for this message, but the recommendations are for Chrome, and I can't seem to find the settings in Edge that correspond. I'm not blocking cookies. But to be sure I've added https://login.microsoftonline.com/ to allowed site.

I can log in on other browsers. I have logged in to DevOps in Edge in the past.

Edge version 103.0.1264.49, 64-bit

    Does it work if you add a new profile in Edge and sign in using that profile? Pay attention when you sign in there might be a prompt which asks you if you want to switch profiles. Please don't switch profile and make sure you're using the new empty profile to login.

    Hi @Nancy Folsom

    Please navigate to edge://settings/content/cookies in Edge and make sure Block third-party cookies is turned off. Please refer to the settings below:

    Besides, you can try to login in InPrivate window in Edge. If it can login in InPrivate mode, the issue might be related with cookie and cache. You can try to clear browser cookies and cache in edge://settings/clearBrowserData then test again.
