Have reviewed quite a few Q&As on this but remain uncertain. Here is scenario: Brand new PBI Service in private email domain let's call it: Sam@A.com
Has trigger a Pro service so is in the initial free Pro PBI Service phase. Has NOT established as Admin because that requires appending the text to his domain which he hasn't yet been able to accomplish.
Has a test dashboard set up that he can view fine. Would like to share test dashboard with 2 users in outside domains. Jim@B.com and Sue@C.com. The Share process gives the yellow warning that the party is outside the domain - but appears then to allow the email to get sent.
At this point behavior differs: Jim@B.com never receives an email. (tried twice); Sue@C.com received an email but then isn't allowed to view dashboard.
I am guessing the issue is that it is either the Pro service in the initial free phase is restricted, or because the Admin role has not yet been established. Advice?
