I know PowerApps cannot be shared externally. However, what about custom forms created by PowerApps if the external user has PowerApps in their subscription. They would be consuming the app and not creating any.
When I am attempt to use the form from an account that does not have PowerApps I get:
“You need a current plan or trail to use PowerApps”
My apologizes if this is a duplicated question. A lot of what I could find related to an app and I am not sure if the forms and apps are treated differently.
