If you have ignored a payment and want to assign it to a contract, here’s the process to do it correctly:
Go to "Account settings".
Select the option "My Bank Accounts".
Identify the relevant account or card where the payments are received.
To help you locate it, you can always specify the period during which the payments were received and the account number of the payer.
Once the payment is identified, click on the three dots "..." next to the "Ignored" label, then proceed to assign it to the appropriate contract.
