I tried the solutions listed, but none worked for me. When I was trying to connect my Chase credit card through the Desktop app, I kept getting a pop up window from Chase saying I needed to update my browser through QBO. I updated my browser (Chrome), but that was the browser on my computer not within QBO. So, I logged into QBO through my browser (rather than the QBO desktop app), and that did the trick! I could see all of the CC transactions that refused to download previously through the QBO desktop app. Then, I checked through my desktop app, and it had updated as well. So, use the browser not the QBO desktop app to reconnect to Chase. I hope this helps!
