Hi, c20kah. Invoices failing to send from the QuickBooks mobile app despite confirmation are typically caused by sync errors between the device and server, often triggered by outdated or cluttered cached data interrupting the connection.
To fix this, I recommend refreshing your app data by going to the Menu, selecting the Settings (Gear) icon, and choosing Refresh Data. This process will update your data and resync your connection. If you still don’t receive invoices in your email, uninstall and reinstall the app. Your data is securely stored in the cloud, so you won’t lose any information.
Additionally, check if you input the correct email address in the invoices. Be sure to check your Spam, Junk, and Promotions folders, as these are sometimes accidentally filtered out of your main inbox.
If you have any other questions or concerns, feel free to leave a comment in this thread.
