I applied for a UK visit visa and had disclosed my previous refusal, However, I accidentally mentioned the wrong year(2021 instead of 2022) but the correct Month, I also enclosed the refusal letter and a copy of the email I received for the refusal that contains the application number too. I had already done my biometrics.
I want to know if this is a significant mistake or something that can be done or if should I just leave it as it is cause there is little I can do now.
