Redirect: Must use browser in app?

I understand that you're experiencing difficulties with the Receipt Snap feature in the QuickBooks Online mobile app, @cedric4. I'm here to assist you with resolving this issue and ensure that you get back to business in no time.
 

First, yes, you're right that the Snap Receipt feature is only available in the mobile app and it should work perfectly. That being said, the error message that you're getting which is to perform it on the browser instead shouldn't be an option.
 

With this, let's perform some troubleshooting steps as this can be caused by some data issues on the app. You can follow the steps below depending on your phone.

For the IOS version:

1. Go to the Menu icon and tap Help & Feedback.
2. Select Refresh Data.
3. If you get a prompt message, "Caution. If there was a problem getting your latest QuickBooks Online data, you can refresh it now. It may take a few minutes."
4. Tap Refresh to confirm.
    
    

For Android:

1. Go to the Menu icon, then tap More Options ⋮.
2. Tap Settings, then Refresh Data.
3. Select YES to confirm.

I'd suggest utilizing the Snap Receipt feature then and see if it's now working as expected. If the issue persists, I'd suggest getting in touch with our Technical Support Team so this will be sorted out in a safe and secure manner using their tools.

In addition to the snap receipt feature, here's an article that you may find helpful in emailing your expense receipts and bills to get them into QuickBooks Online: Email receipts and bills to QuickBooks Online.

I love this, but we can't even get to the 'resync' part in the app. The 'go to the website' thing is an overlay and blocks all interaction with the app. Z-layer problems.
