Why do expenses entered on the mobile app in April still show in March seems the system is not recognising the next month! Anyone else had the same issue?

Let’s perform some basic troubleshooting steps to get you back on track, bobchallacombe.

QuickBooks Online (QBO) on the web and on your mobile app data should always be in sync together. The expenses data should be the same on both. We can change the data connection on your device. If you're connected to Wi-Fi, turn it off and use cellular data and vice versa.

Then, open QuickBooks again and access the Expenses menu. If you get the same result, close and restart the app. Then, refresh the app by going to your settings. Here's how: 

1. Tap the Menu button.
2. On the top-left corner of your screen, tap on the Gear icon.
3. Scroll down and select Refresh Data.
4. Press Yes when prompted.

Also, make sure you have the latest app version installed on your Android device. If you have an outdated version, uninstall and reinstall it to fix the invoice issue. Just download the app again from the Google Play Store. Here's an article you can refer to for more details about QuickBooks Online mobile app. This provides you with information on apps that are available for download.
