A supplier of ours sends QB invoices and for years, we've paid with our business checking account.  The last month or so, no dice.  We get all manner of error messages from payment declined to try again later.  It's the same account we've used for years but now we can't use it.  Supplier mentioned he has other customers who are unable to pay his invoices either, starting with the recent software update.

When will this be resolved?
