You mentioned that you haven't had the time to check on your PC. However, it's best to log in to the web version and check if it's only happening in the app.
In the meantime, let's refresh the program to restore customer-related data and transactions.
If you're using an iOS device:
- Go to the main Menu ☰ and tap Help & Feedback.
- Tap Refresh Data. You will receive a message that says “Caution. If there was a problem getting your latest QuickBooks Online data, you can refresh it now. It may take a few minutes.”
- Tap Refresh to confirm.
If it's an Android device
- Go to the main Menu ☰ then tap More Options ⋮.
- Tap Settings then Refresh Data.
- Select YES to confirm.
Once done, reinstall the app and check if you can see your customer data once again.
