We are doing some testing to allow some guest devs in our tenant and while I can do the invite and gain access when I close the browser and log back in using the email address I was invited from I only see my own 365 portal and clicking my photo in the upper right does not offer a way to switch tenants or access the guest tenant. I can copy and paste the link from the invite to gain access again but this really is not ideal. How should this work? What's the special magic so I'm accessing the company data as a guest and not my own 365 portal? Eventually we need to grant dynamics access which will probably prove even more fun.
