1. In the Maker Portal, why can't you just CREATE the dataflow in a solution? Why do you have to create it under the environments Dataflows and then try to Add Existing?
2. More immediately though: When I create a Dataflow in the environment then publish it and then create a solution and go to add existing and choose Automation | Dataflow, it doesn't show any Dataflows inside or outside.
3. If I have a published Dataflow in one environment and then create a new environment shouldn't I then see it as an Outside option when trying to add existing?
