It would be nice if I could sign up for the service.
When you try to sign up it tells me my email already exists and to sign in with it. After I sign in I am taken to a office page. With no way to sign up for Power BI. There is no for me to sign up for the service. There are also no options for any kind of support what so ever. This is a very bad first impression. I doubt anyone will read nor answer this. This is very frustrating.

This happens after you sign up as well. After using Power BI for about 6 months with a company email address, you may find your sign-in email no longer works and you will no longer have access to publish data. You will also no longer be able to sign-in online either. Microsoft Support is aware of the issue and despite multiple attempts to fix the problem isn't able to find a solution yet and haven't committed to fixing this in 2017.

I am also facing the same issue when I try to signup for Power BI.
