Export to Excel from Power BI Service

I have a number of reports where the users in the past could export data from a table to Excel. Suddenly this option is no longer available for some of the users. In fact, only one of my users can see that option and that person is a CRM admin. I don't know if that's the reason, but that's the only thing that is different from all other users.

Has there been a recent change affecting this option? I have gone through and made sure that the relevant options have been unticked/ticked in the desktop, so things should work. 

Any ideas would be appreciated. Getting pretty frustrated when things that in the past worked fine suddenly stops working :-(
