Dashboards loads but looks wrong
This is most likely an issue with the configuration of the Size and Layout of the Dashboard in Tableau. Take a look at the docs at: https://help.tableau.com/current/pro/desktop/en-us/dashboards_organize_floatingandtiled.htm#set-overall-dashboard-size
One of the most important areas to look at is the “Size” section. We have seen how customers had this set to “Phone” and it made everything appear as a column when embed.
