I am using the Mac QuickBooks Online desktop app. I can no longer open more than one tab because I either get an error or it logs me out. Anyone else seeing this?

I've got some troubleshooting steps we can perform to get the Multiple windows feature working, lutherkitahata.

I've checked here on our end and there's no reported case about this one. It's possible your app's cache data is full of unnecessary data or damaged. We can clear the cache in the QuickBooks app to refresh it and resolve any odd behavior while using it. Here's how:

1. Go to Help on the top menu. 
2. Choose Reset App Data.
3. Then, close and re-open your QuickBook App for Mac.

Once done, open a new window from the top menu. Let me show you how:

1. Go to Window at the top.
2. Select Menu Items Open New Windows.
3. Add a check on the box next to Menu Items Open New Windows.

If the same thing happens, let's uninstall and re-install the app to fix any damaged components on your QuickBook App for Mac. Just follow the steps and details in the QuickBooks App for Windows and Mac: General support article. Then, proceed to How do I uninstall the app? and How do I install the app? section.

Visit our Connect products and apps page for more insights about connecting, syncing, and using apps with Intuit products.

Thanks. Reseting App Data seems to have done the trick. 

I have two QuickBooks Online accounts. One is a QBO Small Business account for one business and the other is a QuickBooks Proadvisor account for my other business. This seems to have started happening after I logged into my Proadvisor account for the first time in the QBO desktop app. Previously, I had only logged into the QBO desktop app with my small business account and I had used the web browser to log into my Proadvisor account. Could switching back and forth in the QBO Mac desktop app be causing the problem? If so, is there a solution for this that allows me to switch back and forth?

Hello there, ben74789.

Switching from one account to the other or every time you access QuickBooks Online, the app accumulates cache. Cache helps browser's or app's background processes. However, too much of it can also cause issues. That's why the Reset App Data helps clearing cache on the app.

On the other hand, the app needs to be updated to ensure that buttons and other features work accordingly. Also, make sure that the app is compatible with the device. You can use this link to know more about it: QuickBooks App for Windows and Mac - General support.
