I have multiple bank accounts and I am trying to transfer money between them. Two of the accounts (A&B) are with the same bank and I am trying to transfer money to another account (C) which is with a credit union.
My bank lets me add the credit union (C) as an external account to my bank account A. However, when I try to add the account (C) to the bank account (B) it stops with an error message because I cannot link the same account (C) with (A) & (B). Is this limit coming from my bank where I have the bank account A & B or is this issue coming from the credit union (C)?
Can I solve this problem by opening an account (D) at another bank and closing A or B? These are all personal accounts and I would like to keep my finances separate. I would like to avoid writing myself checks. Unfortunately services like Zelle are not available with the credit union.
