I've made a quick video to show how you can enable the new Ribbon Menu in Power BI Desktop.
In the February 2020 version of Power BI Desktop this is still a "preview" feature, so you need to enable the preview to see it. However this new menu is expected to be on general release sometime in March this year, so it's probably a good thing to enable this menu now and get used to it before the March update enables it for everyone.
We run probably the best Power BI training courses in the UK.
Public courses run in London, or we can run an on-site course for you anywhere in the UK or overseas.
