I have a dataflow in Premium P1 that has been refreshing for several days now. It isn't a big query and I've tried about everything to stop it. It is not actually connecting to the database it's supposed to be querying, It's just running. I can't delete it, stop it, or have any effect on it. I've tried switching the gateway, deleting the data source, and restarting the service. Is there anything else I can do?
