I made several attempts since November 2022 to change my bank account number, reporting the problem and always the same response without helping me and solve this BUG, result my store is suspended and I never received my money.
@GreenTerreHappyParis: DO NOT open a new issue or contact Etsy multiple times about the same issue (doing so closes the one you already opened and puts the new one on the bottom of the pile). Every eMail from Etsy support should have a link something like "I Still Need Help". Click on that link (or actually reply stating that you still need help) to keep the report alive or Etsy will assume that it is resolved. You may have to do this innumerable times before anything is done but do not give up.
Is the bank located in France?
