Fix 'Cannot Access Forms' Error in SharePoint Mobile App

Product: Microsoft SharePoint
Device & OS: iOS and Android
Scenario: Attempting to view or fill out an embedded Microsoft Forms web part from within the SharePoint mobile app.
Observed behavior: The form displays a 'Cannot access Forms' error in the Android or iOS SharePoint app, despite working normally on desktop and mobile web browsers.

Before you start

Make sure your device has a default mobile web browser installed (such as Safari for iOS or Google Chrome for Android) to easily apply the recommended workaround.

Use the 'Open in Browser' Workaround

Bypass the in-app rendering issue by forcing the SharePoint site to load in your device's native mobile web browser.

Currently, this error is a known compatibility issue following a Microsoft 365 update. The Microsoft Forms web part fails to load natively inside the SharePoint app environment. Until Microsoft releases a permanent fix, opening the page in an external mobile browser is the only confirmed way to access your forms on a mobile device.

Open the affected SharePoint page

Launch the SharePoint mobile app on your iOS or Android device and navigate to the specific site or page where the 'Cannot access Forms' error is displayed.

Access the app menu

Locate and tap the menu icon (usually represented by three horizontal dots or lines) in the upper-right corner of the SharePoint app interface.

Select 'Open in browser'

From the dropdown menu, tap on 'Open in browser' or 'Open in Safari/Chrome'. This action redirects you out of the app and loads the exact same SharePoint page in your default mobile web browser.

Access your form

Once the page loads in the mobile browser, scroll down to the Microsoft Forms web part. It will now display and function correctly, allowing you to fill out and submit the required information.

Ongoing Microsoft Support Investigation: Microsoft Support is aware of this escalation and is actively investigating the compatibility bug. Keep your SharePoint mobile app updated to ensure you receive the official patch once it becomes available.

Frequently Asked Questions

Why does Microsoft Forms work on my computer but not in the SharePoint mobile app?

This is caused by a known mobile compatibility bug following a recent Microsoft 365 update. The SharePoint app currently struggles to render the Forms web part internally, whereas desktop browsers process the embedding code correctly.

Will clearing the app cache fix the 'Cannot access Forms' error?

No, clearing the app cache or reinstalling the SharePoint app will not resolve this issue. Because the bug lies in the app's current codebase, you must use the 'Open in browser' workaround until Microsoft releases a formal patch.

Can I still submit my form responses using a mobile device?

Yes. While the form won't load directly inside the SharePoint app, utilizing the 'Open in browser' option from the app's top-right menu will load the form in Safari or Chrome, where you can submit it without any errors.
