Let's work together so we can narrow down the root cause of this issue and resolve it to help you continue with your task, @mcfhome1.

Before anything else, did you receive any error messages when trying to log in to your QuickBooks Self-Employed (QBSE) mobile app? This will help me identify the root cause of the issue and accurate resolution for you.

In the meantime, I recommend performing some troubleshooting steps on your mobile to help isolate the issue. Sometimes, numerous cached files can cause unusual software behavior. 

For Android devices: 

1. Modify your device's Wifi data connection to 4G (varies by device).
2. Close and restart the app. Then, clear the app data.
3. Once done, power down and restart your device.
4. Uninstall and reinstall the app.

For IOS devices:

1. From your phone's settings, select Settings.
2. Next, click on General and choose iPhone Storage.
3. Select the QBO app. This will free up the storage without deleting the documents and data for the app, select Offload App.
