The Gateway connection settings no more available for dataflows in PBI Services

[BrunoM]

Since last friday, the Gateway connection settings is no more available for dataflows in PBI Services. The option is displayed but cannot be used.

I have created a MS Ticket.
Have you seen the same problem in your organizations?

What solution do you practice to assign a dataflow to a correction Gateway source ?

In advance thank you for your help

Hi @BrunoM 

As per the description you have to edit the connection via Power Query online when you edit the dataflow?

You are right for a workaround solution (that we used) only.
Some explanations: In our organization, the dataflow developper is using a dedicated source that corresponds to his authorization scope. Once the dataflow is developped and ok, another source with a larger data scope will be assigned by an admin. 
In this new scenario, the assigment can be done only if the admin take over the dataflow and modifies it as a developper. This situation do do not match with the RACI of our organization.

I wonder to understand why MS is changing something that was working ... And how they can do that without announcements nor consultations.
