All my expenses have been turned to no category. I can add them again, but my whole history going back years now only shows as no category. Deleted the app but the same.

Welcome to the Community space, @bex_parker.

I'm here to provide some information about your expense transactions that are showing up as uncategorized.

Sometimes, an accumulation of too much cache in the app can cause unexpected behavior with the product, which is why your expenses are showing up as uncategorized. We can reset it to see that causes this issue. This process will help us start again with a clean slate. Here are the step-by-step instructions you should follow:

1. Change the Wi-Fi data connection on your device to 4G (varies by device).
2. Close and restart the app.
3. Clear app data. To do this:

• Open your device, Settings.
• Choose Apps (varies by device).
• Select QuickBooks app from the list, then select Storage.
• Then click clear data.

4. Power down and restart your device.
5. You can also Uninstall and reinstall the app.

However, if you're using the QuickBooks App for iOS, there is still an ongoing investigation regarding QuickBooks iOS mobile app is missing data. The best course of action we can take in the meantime is to reach out to our Customer Support Team and ask them to add you to the list of affected users. You will receive email updates and get notified once it's resolved. To do so here's how:

1. Sign in to your QuickBooks Online company.
2. Select Help (?).
3. Choose either of these tabs:

• QB Assistant, enter the topic you need help with. You can also enter questions.
• Search and select Contact Us to connect with a live support agent.

4. Choose how you want to reach us (phone or chat).

Moreover, I'm adding this helpful article as your reference in reconciling your accounts, so they always match your bank and credit card statements: Reconcile an account in QuickBooks Online.

I’ll be around the corner if you need an extra pair of hands in any QuickBooks-related matters. Stay safe!
