Our team can link bank accounts from Business Central to all of our various banks in Canada. We are, however, having an issue linking a bank account in Business Central to American Express - for two accounts, one in CAD$, one in USD$, and both linked to our Canadian company in Business Central.
I can validate that we can login in with our credentials on the American Express site for both accounts, and we can download transaction details manually.
Our issue is strictly with linking the bank account within Business Central to American Express.
We are getting the following error:

I have seen various posts on deleting the account in Business Central and/or creating a new account and then linking it up - we've tried these actions to no avail.
Anyone seen this issue before and know the resolution?
Thanks!
