XML validation errors when opening Tableau Public workbooks after recent update

Hi everyone,

I'm using Tableau Public and recently updated to the latest version. Since the update, I'm seeing XML validation errors when opening some workbooks downloaded from Tableau Public.

The error includes messages such as:

• attribute 'extension-version'
• attribute 'id'
• no declaration found for element 'worksheet-extension'

This was not happening before the update.

A few details:

• The issue occurs while opening workbooks downloaded from Tableau Public.
• I recently updated Tableau Public and the problem started afterward.
• I am not intentionally using any extensions in my own workbook.
• Some workbooks open, while others produce these XML/extension-related errors.

Has anyone else experienced this after a recent Tableau Public update?

I'm trying to determine:

1. Whether this is a known bug in the latest Tableau Public release.
2. Whether the issue is related to dashboard/worksheet extensions.
3. If there is a workaround other than reinstalling or downgrading Tableau Public.

Any help would be appreciated. Thanks!
