Question details
Users experience text disappearing from a SharePoint rich-text field when editing list items in Grid View.

- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Editing SharePoint list items containing rich-text fields in Grid View while using a Power Apps custom form.
- Observed behavior
- The text stored in the rich-text field disappears upon editing because the Power Apps customized form does not support the 'Append Changes to Existing Text' feature.
Ensure you have site owner or full control permissions for the SharePoint list to modify column settings and create Power Automate flows.
Disable Append Setting and Retrieve History via Power Automate
Since Power Apps customized forms do not support appending changes, you must disable this setting and use a Power Automate workaround to display version history.
The core of this issue stems from a compatibility limitation between SharePoint's 'Append Changes to Existing Text' feature and Power Apps customized forms. Disabling the feature stops the text from disappearing, and you can restore historical visibility using the SharePoint REST API.
Navigate to your SharePoint list settings, select the affected rich-text column, set the 'Append Changes to Existing Text' option to 'No', and save your changes.
Open Power Automate and create a new flow triggered by selecting or modifying the specific SharePoint list item.
Use the 'Send an HTTP request to SharePoint' action within your flow to call the SharePoint REST API and retrieve the item's version history.
Add a gallery control in your Power Apps customized form and bind it to the data returned by your Power Automate flow to display previous rich-text entries.

Frequently Asked Questions
Why does the rich-text field disappear in Power Apps?
Power Apps customized forms currently do not support the 'Append Changes to Existing Text' feature used in SharePoint lists. When this feature is active, Power Apps fails to render or save the text correctly, causing it to disappear in Grid View.
Can I still view the historical text if I disable the append setting?
Yes, the historical data remains safely stored in the SharePoint version history. You can view it by checking the item's version history directly in the list, or by using the REST API to pull the data into a gallery.
Will Microsoft fix this Power Apps limitation?
Microsoft monitors user feedback through the Power Apps Ideas platform. Submitting a feature request there is the most effective way to encourage the product team to add native support for appending text in future platform updates.
