Is there a setting for snapping receipts? Everytime I take a photo of a receipt on the app it says it cannot upload?

Hi -mielesgelateria, thanks for joining the Community. 

There are no settings for Receipt snap on the app, this feature will be automictically enabled once the app is installed. We do however only support PDF,  JPEG, JPG, GIF, and PNG images. If you have a newer iPhone or iPad, your images might be in the HEIC format. You can convert HEIC images to a compatible format.

If you're still unable to upload the receipt following this, please uninstall and reinstall the app to troubleshoot. As a workaround in the meantime, you can also upload a photo via the browser version of QuickBooks as an attachment.
