Hello there, @keepingupappeara.

We recognize the significance of having your data to manage your tasks in QuickBooks Online (QBO). As part of our commitment to keeping you informed, I would like to offer you detailed information and support in this regard.

Upon checking here at our end, we have identified an investigation (INV-106520) with data access for iOS users, and our product engineers are actively working on a solution. In the meantime, I recommend contacting our Online Team support to be included in the list of affected users. Once added, you will receive email notifications regarding any updates on this issue. Here's how to reach them using the browser:
 

1. Log in to your QuickBooks Online company.
2. On the upper right corner of your screen, click on Help (?).
3. Select or type Contact Us.
4. Start entering your concern, then select Let's Talk.
5. Select either of these tabs:

• Assistant tab and select Talk to a human.
• Search tab and click on Contact Us to connect with a support expert.

However, if you're using an Android device and encountering issues, we can troubleshoot to rule out the root cause. Device problems can often be related to storage space or app content, so here are some steps to address the issue:
 

1. Modify the Wifi data connection in your device to 4G. (Depends on devices).
2. Close and restart the app.
3. Clear the app data.
4. Power down and restart your device.
5. Uninstall and reinstall the app.
