When I update the URL of my product on my store the app keep feeding the old incorrect URL to google merchant causing my account to get suspended. Try yourself
During your 90 minute session, you have disabled the auto-update feature of the app. This is probably why the URL was not updated. So it's not a bug - it's a feature: When a merchant disables auto-update - the app will not update your feed.
Which one of your store's two products have you updated? If you reinstall the app and contact our support - we will be happy to help you out.
