Tile and report not updating after file in Onedrive for Business is

[MiguelMartinez]

I have an excel Power Pivot model that feeds a dashboard in Power BI through OneDrive for business. Even though I have no blanks on the model, the tile and the report show blanks on the legend and the actual data.

I know the report has the latest data since I keep record of the latest date and it;s showing up on a Q&A tile I created to display update date. Any idea what's wrong and how to fix it?

If you've made breaking schema changes, it is possible that tiles that use the now-invalid parts of the schema will no longer refresh.  Is that the case in your situation?
