Charting block preview page different from published page for same user

Hi

I have a charting block based on an airtable table. The chart is a bar chart filtered on an attribute of the logged in user. When I preview the page with a particular logged in user I see the chart properly, but when I publish the page and log into the app as the exact same user as preview, it says no data. But I know there is data and it shows up on preview. Looks like a bug
