I just started using TabCMD to export PNG files from our Tableau Online instance. Is there anyway to remove the Tableau logo that appears at the bottom of the exported PNG file? It does not appear when I manually export from the workbook itself.
This is surprising. I can see the behavior you describe and I'm unable to reproduce on Tableau Server (where I don't see the logo). Have you created a support ticket? I'd suggest you do if you haven't already: Support Case | Tableau Software. Support can either confirm that's the expected behavior or provide more context/options.
