PowerBI Report pages being removed when data refreshes

[AFisher1]

We are seeing an issue with a Power BI report removing pages after a data refresh. 

A page is added to the report and visualsations are added by a contributor within the workspace. These changes are saved and visibile within the workspace. 

The data is refreshed from a semantic model from a CSV, The changes from the contributor are removed. 

If the creator of the report follows the same steps the changes are saved after refresh. 

Has anyone seen similar?

Thanks for your response, There are no apps involved only workspace at this point

The data is refreshed from a semantic model from a CSV, The changes from the contributor are removed.

Please explain in more detail.  Did they add a page and that page disappeared?  Was it visible when they uploaded to the workspace?  Is the page maybe set as hidden?  Does the semantic model have scheduled refresh set up and enabled? Do you observe a refresh kicking in after upload?

Are apps involved or is this workspace only?
