Email Subscription - Report Preview - Outdated

Hey umali  , 

This issue can happen in Microsoft Power BI because the email preview and the attached PDF in a subscription are generated in different ways. The preview image that appears inside the email is usually taken from a cached snapshot of the dashboard or report in Power BI Service. Because it relies on cached visuals, it may sometimes show data from a previous refresh. On the other hand, the PDF attachment is generated at the time the subscription runs, so it pulls the latest available data from the semantic model. That is why the PDF often shows the correct and updated data while the email preview occasionally looks outdated.

A common way to reduce this issue is to make sure there is enough time between the dataset refresh and when the subscription email is sent. If the subscription runs immediately after the refresh, the dashboard tiles might not have finished updating their cache yet. Scheduling the email subscription a bit later (for example, 20–30 minutes after the refresh) usually allows the visuals to update properly so the preview and the PDF match. Another option is to subscribe to the report instead of the dashboard, since report subscriptions tend to render more consistently with the latest data.
