Some others have mentioned a similar issue in the Moodle discussion board. You can pass a parameter that disables the auto-login, and this can fix it. Edit your oauth-issuer for Microsoft and add the following in the field "additional login parameters": "prompt=select_account" https://video2.skills-academy.com/en-us/azure/active-directory/develop/v2-oauth2-implicit-grant-flow
Let me know if this helps at all. Others have said that you just need to wait it out, which isn't ideal...
