- Scenario
- Users are attempting to attach files and submit customized SharePoint forms, but submit the form before the attachment control finishes loading or while experiencing unstable network connections.

Consult the Microsoft Power Platform Community
Since this issue involves complex integration and customization between Power Apps and SharePoint, reaching out to dedicated experts is the most effective approach.
The standard SharePoint support channels primarily focus on built-in features. Custom forms built with Power Apps have unique submission formulas and attachment control behaviors that require specialized diagnostics.
Collect important details including your form configuration, attachment control settings, the exact SubmitForm or Patch formulas you are using, and browser details.
Note exactly when the attachments fail to save, such as during slow network conditions or specific file types.
Visit the Microsoft Power Platform Community Forum (community.powerplatform.com) and create a detailed thread under the Power Apps section containing all your gathered information.
Verify Attachment Control and Submission Settings
Perform basic checks on your Power Apps formulas to ensure the attachment control is properly linked to the SharePoint list update property.

Frequently Asked Questions
Why do attachments fail to save in SharePoint Power Apps forms?
This commonly occurs if users click submit before the attachment fully uploads, if there are sudden network drops, or if the form's data card update property is disconnected from the attachment control.
How can I prevent users from submitting the form before attachments load?
You can modify the 'DisplayMode' property of your Submit button in Power Apps to be disabled (DisplayMode.Disabled) while the form is saving or while an upload process is incomplete.
Can I revert my Power Apps customized form back to the default SharePoint form?
Yes. Navigate to your SharePoint list, click the gear icon to access List Settings, select 'Form Settings', and check the option for 'Use the default SharePoint form'.
Does file size affect saving attachments in Power Apps?
Yes. Power Apps attachment controls have a maximum file size limit, which defaults to 10MB but can be increased up to 50MB. Files exceeding this limit will silently fail to upload.
