Data not refreshing

[PaulButler]

I have a Power BI report (let's call this Master) which connects to SQL to get it's data.  Gateway all setup and refreshes daily.  I also have a second Power Power BI report (let's call this User) which uses Master as it's data source, connecting using analysis services (Import Mode) with Microsoft Account as authentication.  I publish this report and all works fine.  I'd expect that when Master refreshes daily, User should just update too but this is not happening.  If I look at the dataset for User you can't configure anything to do with refreshes or gateways (says I don't need one as the source is in the cloud).  If I try a manual refresh I get the following error.  Any help would be appreciated.

In dataset settings -> Data source credentials -> Oauth2 and login with the applicable credentials
