Are you trying to confirm a transaction from the Banking page? Can you please provide a sample screenshot where you got the error message? Do you also have a user working on the account at the same time? This is for us to check the meaning of the message.
Please feel free to leave a reply below and I'll get back to you as soon as I can. Thank you in advance for any details you can provide. Stay safe!
