If you would like to remove the PayPal app from your QuickBooks Online UK account, you can follow the steps below:

1. Log in to your QuickBooks Online account.
2. Navigate to the Apps section by selecting Apps from the left navigation menu.
3. Click on My Apps to view the list of apps connected to your account.
4. Locate the PayPal app from the list.
5. Next to the PayPal app, select the drop-down menu (usually represented by three dots or lines).
6. From the drop-down menu, choose the option to "Disconnect" the app.
7. Confirm the action when prompted.

Please note that only the user who added the app will be able to remove it. If you did not add the PayPal app, you may need to reach out to the user who added it or the account administrator to have it removed.
