Hello, @cfbrandtjewelers. It can be concerning when an app freezes, especially when you're trying to manage QuickBooks Online (QBO) efficiently. Let's remove the app so you can get back to business without interruptions.

Here's how to disconnect an installed app if you're the user that connected it:

1. Navigate to the Apps menu and choose Overview.
2. Look for the app you want to disconnect.
3. Select the dropdown next to Launch, then Disconnect.
4. Complete the brief questionnaire.
5. Click Disconnect to remove the app from your company profile.

If the app is unresponsive, let's perform the procedures above through an incognito window or other supported browsers. This unexpected behavior likely caused by a browser or cache-related issue. Here are the shortcut keys:

• For Mozilla Firefox browser: Ctrl + Shift + P
• For Google Chrome browser: Ctrl + Shift + N
• For Safari browser: Command + Shift + N

On the other hand, if you didn't integrate the app, you can follow the steps in the section titled "If you're not the user that connected the app" in this article: Disconnect an app in QuickBooks Online and QuickBooks Online Accountant.

In case you want to change app ownership, refer to this article for guidance: Transfer app ownership or disconnect apps in QuickBooks Online and Accountant.
