SuperTables keeps reloading in Tableau Desktop

Cause: This issue is caused by a known sync bug in Tableau Desktop, not in the SuperTables extension itself. When you configure a worksheet and add it to a dashboard simultaneously, Tableau tries to sync both views, but because they are treated as separate instances, this sync fails and causes the extension to repeatedly reload.

Symptoms:

• SuperTables view and the “Format extension” panel constantly reload

• Restarting Tableau sometimes helps, but the issue returns

• Happens mostly when configuring the worksheet and dashboard at the same time

Resolution / Workaround: While Tableau works on fixing the sync bug, we recommend:

1. Remove SuperTables temporarily from the dashboard while configuring the source worksheet

2. Only add the extension after your worksheet is fully prepared

3. Avoid editing both the worksheet and dashboard in parallel while the extension is active
