Apologies for the delay in getting back to you. Older threads don't include post notifications, so it's best to start a new thread with any questions you have in the future as this will ensure a speedier response! Diving into your question, is it that your routing number wasn't accepted, or is it that a payout hasn't arrived? If could follow up with as much detail as possible, then I'd be happy to take a look.
If the error is that the number is not found, then you'll want to ensure there are no additional spaces or additional numbers added. If that doesn't resolve the issue, then you'll need to speak with your bank directly to ensure the routing number is correct.
Is the bank you're trying to add considered to be an online bank, or does the bank have physical brick and mortar locations? If it is an online bank, then this bank type would be unsupported and would require using a bank that has physical locations within your country. If your bank does have physical locations, and you're still having this issue then let me know as I can verify the store to take a look.
