I haven't been able to connect to the server for a long time through the app. I can't create invoices, estimates, nothing. How do I fix this? Thanks!

Hello there, jdhenley87.

I recognize the impact of this challenge on your business operations due to the inability to connect to the server via the app. Rest assured, I am committed to swiftly assisting you in resolving this matter.

If you are using an Android device, there's an investigation into this issue. Currently, our product engineers are implementing a solution. I suggest contacting our QuickBooks Support experts to add you to the list of affected users and receive updates once it's available.

In the meantime, you can create invoices or estimates through a web browser.

However, if you're using an iOS device, you can fix this by clearing the app's cache. There are instances when the app has a large amount of data, resulting in strange results. 

To clear the cache in your QuickBooks Online app, follow the steps below.

• iOS - Tap the Menu at the bottom and click on Help & Feedback. Then select Refresh Data and Refresh.

To clear cache in your phone settings:

• iOS - From your phone's Settings, choose Settings. Click on General and choose iPhone Storage. Select an app that's taking up a lot of space. To free up the Storage without deleting the documents and data for the app, select Offload App.
