Is it possible to delink my bank from quickbooks in the app please.

Hi there, @gibson-marimanzi.

I appreciate you for reaching out to us here in the Community. I can help you unlink the bank account in QuickBooks Online.

QuickBooks Online mobile app allows instant access to your data from your mobile device. However, there are some limitations when using the app. I suggest logging into your account using a web browser on your device and disconnect your bank there. It works the same with how you access your account on your computer.

Here's how:

1. On the left navigation bar, hover your cursor to the Banking or Transactions menu and choose Banking.
2. Select your bank account.
3. Click the pencil ✎ icon, then Edit account info.
4. Put a checkmark on the Disconnect this account on save checkbox. 
   
5. Hit Save and Close.

You can also check this resource for more details about importing bank transactions for accounts connected and not: Manually Upload Transactions.
 

Lastly, you'll want to review the comparison of available features on different devices with this link: Compare Mobile App Features.

Keep me posted with your result after unlinking your bank. I want to make sure everything is taken care of. If you also have any other questions related to banking, feel free to comment down below. I'll be happy to help you some more.
