When I try to connect with Microsoft graph with a personal acount, I get this error message: AADSTS7000012: The grant was obtained for a different tenant.
I am following this tutorial https://github.com/Azure-Samples/ms-identity-java-webapp/tree/master/msal-java-webapp-sample, and it works fine with professional account.
Also I don't find any documentation on this AADSTS7000012 error code!
