Hi @kathrin,
As of this time, there isn't an option to remove banking alerts in QuickBooks Online.
This is to notify our users like you since we continue to receive updates from your bank.
In the meantime, I'd recommend contacting our Customer Care Support. This way, you'll be able to confirm if there's a connection issue with your bank.
Here's how you can contact our support:
- Go to Help.
- Select Contact us.
- Enter Citizens Bank in the How Can we help? field.
- Click Continue.
- Select Start messaging or Get a callback.
In addition, here's an article you can read to learn more about contacting our support: Contact the QuickBooks Online Customer Support Team.
Please let me know in the comment section below if you have any other questions. It'll be always my pleasure to help.
