The user needs to fix a custom Power Apps form integrated with a SharePoint list that renders at an unexpectedly small size and centered on the screen after publishing.

How to Fix a Power Apps SharePoint Form That Is Too Small and Centered

Product: Microsoft Power Apps and SharePoint
Device & OS: not provided
Scenario: Publishing and viewing a customized Power Apps list form within a SharePoint Online environment.
Observed behavior: The form displays correctly and at the proper scale within the Power Apps editor, but shrinks to a small, centered layout once published and accessed through SharePoint.

Before you start

Verify your SharePoint and Power Apps environment details, and ensure you have the exact URL components for your SharePoint site and list readily available.

Solution 1Recommended

Use a Direct URL to Access the SharePoint Form

Bypass the embedded SharePoint view by opening the new form page directly via its specific URL. This is the most effective workaround for temporary rendering bugs.

This issue is often associated with Microsoft service incidents, specifically SP907551, which affected the alignment and sizing of SharePoint Online custom forms.

By accessing the form's direct URL, you force the browser to render the Power Apps form outside the problematic embedded SharePoint frame.

Identify your site and list details

Take note of your SharePoint tenant domain, the specific site name, and the exact name of your SharePoint list.

Construct the direct URL

Format a URL using this template: https://yourdomain.sharepoint.com/sites/sitename/Lists/listname/newform.aspx. Replace 'yourdomain', 'sitename', and 'listname' with your actual environment details.

Access the form

Paste the newly constructed URL into your web browser's address bar and press Enter. The form should now load at the correct size.

Workaround Status: This direct link method ensures users can continue submitting data without experiencing the severe shrinking issue while awaiting permanent updates.

Solution 2

Verify the SP907551 Incident Resolution

Check if your tenant has received the fix for Microsoft incident SP907551, which resolves the root cause of the form sizing issue.

Frequently Asked Questions

Why does my Power Apps form look different in SharePoint than in the editor?

This discrepancy happens because the SharePoint environment applies its own CSS and embedding frames to the published form. Occasionally, Microsoft service bugs (like incident SP907551) disrupt how these frames scale the Power Apps canvas, causing it to shrink.

Has Microsoft fixed the SharePoint form sizing issue?

Yes, Microsoft identified the custom form alignment and sizing issue under incident SP907551 and deployed a fix on October 10, 2024, at 5:00 PM UTC. Ensure you clear your browser cache to see the updated fix.

How do I find my SharePoint list URL to bypass the form error?

You can locate your base URL by opening your SharePoint list and looking at the address bar. It typically follows the format https://[tenant].sharepoint.com/sites/[site-name]/Lists/[list-name]/. Append 'newform.aspx' to this path to access the form directly.
