Yes it works with 9.0, but IIRC not all features do...
The 8.5 BETA was invite only. This is not. Invites do not exist. Therefore, how can Microsoft detect when a user is just signing in with an alternate email address in the BETA? One machine/person can use multiple addresses.

That means it could take even longer for it to be released. You are obviously having compatibility issues and have not been invited to use it, so my advice is to remove it fully from your system or gtfo.
