I'm having the same issue. When I receive the email confirming that I can start using RemoteIE, I sign in and every time I get the notification that I don't have access to any RemoteApp programs and if I would like to try the demo apps.

Is there something going wrong with the service? I'm trying to load it multiple times and every time it's the same.

FYI. I'm using the same Microsoft account/email, I've selected West Europe and I'm using the latest version of Microsoft Remote Desktop (8.0.10).

I've just tested it with North Europe and that one works. I think there might be an issue with the Western Europe location.
