Cannot schedule refresh with Smartsheet data?

Charles, here's a response I got from Microsoft support so I think this ticket is prematurely closed. Hi Adam, I received word back from the PG. It seems, at this time the gateways do not support the cloud SaaS connectors therefore giving you an error stating that the source kind is not supported. An ETA for a fix rollout is not yet listed but I can see that this is a known issue that they are working to resolve now. I encourage you to monitor the support page because when a fix is being rolled out it will be listed on the Power BI support site. I’m sorry for any inconvenience that this may cause and thank you for contacting Microsoft Pro Support Adam.
