Hi longwang-boringt,
Welcome back to the Community. QuickBooks Online is a powerful program that's designed to help you streamline your work. I'll be glad to provide more info and make sure you're on the right track with achieving your QuickBooks goals.
QuickBooks Online operates and stores data on the cloud. This means that your data is available to you wherever you have a reliable internet connection. Based on what you've described, I recommend checking to make sure you're logged in the correct account in the mobile app. I also recommend making sure you're connected to the internet when logged in the app.
