[Updated Date] Power Platform - Information about SharePoint file thumbnail changes

🚨 The Signal: SharePoint file thumbnail URLs in Power Platform flows will become invalid after September 1, 2026. Flows must be updated to use a new 'Get file thumbnail' action that returns an image directly, preventing potential workflow failures.

The Impact

Power Platform administrators are affected, facing a low risk of workflow disruption if flows are not updated.

• Power Platform admins: Risk of broken workflows if not updated.
• Business users: Potential disruption to automated processes relying on thumbnails.

The Action

1. Identify all Power Platform flows and agents that use SharePoint triggers or actions returning thumbnail URLs.
2. For identified flows, locate the 'thumbnail URL' dynamic content usage.
3. Replace the existing thumbnail URL logic with the new 'Get file thumbnail' action.
4. Configure the new action to return the image directly.
5. Test updated flows thoroughly to ensure continued functionality.
