Hi Daniel,
I can see how important to you and your business to be able to connect Peoples Choice Credit Union bank in QuickBooks Online. At the moment the Peoples Choice Credit Union bank is no longer accepting third parties to connect. That is why the connection/integration have stopped for this bank in QBO.
I have re lodged the request to our product engineers for the improvement of connecting banks and ease of recording transactions.
At the same time, as a workaround, we advise to manually upload the bank transactions via CSV file so you can still continue categorising and recording your transactions from that bank. Here's some articles you can check:
Post again in the Community if you have other banking concerns.
