Just to make sure there are no spaces after you add the - also and to write the full year (1986 for examples instead of 86).
Hi @katherinezz, we wouldn't be able to change, add, or adjust any banking information as it would be too sensitive.
Are you trying to change the bank details in your admin to get paid here or for the billing of your Shopify plan? If you could screenshot where exactly you are referring to (without any sensitive information) it would be a huge help to find out where exactly you mean.
I have reached out to you directly about this. If for any reason you didn't receive an email, please let me know here.
