Describe the bug Our AAD MFA was changed from Office365 MFA to Azure MFA. Before that everything worked. Now, when authorizing in SPA no MFA prompt is showed for user to accept, but user is logged in and access token and id token is returned. Everything seemed fine. Requesting API method, authentication in backend is successful, but when requesting access token on behalf of user exception is beeng thrown: AADSTS50076: Due to a configuration change made by your administrator, or because you moved to a new location, you must use multi-factor authentication to access '00000003-0000-0000-c000-000000000000'. Is it something wrong with our configuration or does this library has problems with Azure MFA? Again with Office365 MFA everything workend.

Expected behavior MFA prompt for user?

To Reproduce Setu up AAD with Azure MFA Try to authorize with library No MFA promt asked
