On the mobile app vendors show no activity when they should show years of activity . Any idea why or how to fix?

Thank you for bringing this issue to our attention, gakers811. My goal is to help you retrieve your data as soon as possible so you can view the activities of your vendors on your QuickBooks Online (QBO) app.

I replicated it on my phone and confirmed that all the activities of the vendors were showing. One possible reason for the problem you’re experiencing could be that you didn't sort by Date and filter to All, which would allow all the activities to be displayed.

Meanwhile, if you have already taken those steps, clearing the app's cache can help resolve many general issues with the QBO app. By doing this, you can remove historical data and access QuickBooks in a clean state.

To start, let's refresh your data to see the latest available information in your QBO app to resolve this unexpected behavior.

Here's how:

iOS

1. Go to Settings, then tap General.
2. Click iPhone Storage, then tap the QuickBooks Online app.
3. Select Offload App.

This will free up the storage without deleting your app's documents and data.

Android

1. Go to Menu ☰, then tap More Options ⋮.
2. Select Settings, then Refresh Data.
3. Click YES to confirm.

If the issue persists, You can uninstall and reinstall the Online mobile application if the problem continues. Otherwise, you can access QuickBooks Online using other supported browsers.

Nevertheless, you can compare mobile app features and see QuickBooks Online access for mobile devices.

To make sure the issue is resolved, please update me on your progress after you try the steps. Feel free to reply to this post, and I will reach out to you.
