Does the extension work on Internet Explorer?
There is currently a bug with IE11 in versions 2018.2.x Tableau Server and our extensions do not work. We have raised this with the Tableau product team and we are hoping for them to implement a fix in the near future. They have not committed to a date yet, but please follow Tableau's release page for the most up to date information, or reach out to your Tableau representative: https://tableau.github.io/
In the meantime, please use Chrome to access our extensions.
