Question details

The user needs to restore the connection between a previously customized Power Apps form and a SharePoint list after it accidentally reverted to the default SharePoint form.

Product: SharePoint and Power Apps
Device & OS: not provided
Scenario: Restoring a disconnected custom Power Apps form to a SharePoint list.
Observed behavior: SharePoint connected to a newly created app instead of the original customized app, resulting in submitted items failing to appear in the list.

Before you start

Ensure you have Owner or Editor permissions for both the SharePoint list and the Power Apps environment, and verify that your original canvas app has not been deleted from the Power Apps portal.

Solution 1Recommended

Verify Data Sources and Reconnect the Original Canvas App

Check the connections within the original Power App to ensure it points to the correct SharePoint list and update the SharePoint form settings.

When a SharePoint list reverts to its default form, switching back can sometimes force SharePoint to generate a brand new app. To resolve this, you must redirect your original app back to your list and ensure the submit functions are routing correctly.

Open the Original App

Navigate to the Power Apps maker portal, select 'Apps' from the left menu, locate your original custom form app, and click 'Edit'.

Check Data Sources

Click on the 'Data' icon on the left menu pane and verify that the SharePoint list connection is active. If it is broken or disconnected, click the ellipsis next to it and select 'Remove'.

Re-add the SharePoint Connection

Click 'Add data', search for 'SharePoint', authenticate your account, and select the exact SharePoint site and list you want to reconnect to.

Update Form Settings in SharePoint

Save and publish the Power App. Go back to your SharePoint list, open the 'Gear' icon > 'List settings' > 'Form settings', and ensure it is set to 'Use a custom form created in PowerApps'.

Check the SubmitForm Function: Ensure that the 'OnSelect' property of your submit button uses the correct SubmitForm(FormName) function and that the form's DataSource property exactly matches the reconnected SharePoint list.

Solution 2

Consult the Power Platform Community

If manual reconnection fails, seek specialized assistance from Microsoft engineers and community experts.

Frequently Asked Questions

Why did my SharePoint list revert to the default form?

This typically happens if a user with sufficient permissions changes the list's 'Form settings' back to 'Use the default SharePoint form', or if there was a synchronization error or glitch during a recent Power Apps update.

How do I find my original Power Apps form if it's disconnected?

Log into the Power Apps maker portal, click on 'Apps' in the left navigation pane, and look for an app named after your SharePoint list (often with the word 'Form' appended). You can also filter the list by 'Canvas app'.

Why aren't submitted items showing up in my SharePoint list?

If items are not appearing, the Power App's form is likely pointing to a broken data source, or SharePoint generated a new, empty list link for the app instead of routing the data to your original SharePoint list.
