I don't have a resolution but I may have an explanation, so you are not waiting for a fix that may or may not happen. I had an instance where my client's bank changed their log in process to a two step function. When a patron goes onto the banks website the patron/client choses online banking but then has to chose if it is for a personal account or a business account. This second choice "broke" the way QBO could access the client's transactions. After speaking with support, I was told that online link between the client's bank and QBO could no longer happen with this 2 step process.
