Best Practices

4. Secure Access: Restrict permissions in SharePoint List settings.

Troubleshooting

Issue	Solution
Data is not showing in the gallery	Check if the app is connected to the correct SharePoint list.
Delegation warnings	Use StartsWith() instead of Filter(), or limit the number of records loaded.
App is slow	Load data into a collection (ClearCollect()) to improve performance.
Users can’t edit data	Check if the user has Edit permissions in SharePoint.
