We appreciate you taking the time to work on your end before posting here in the Community, @elecuyer.
As your bank connection still doesn't sync, the issue may be on your bank's end. Another way to fix this is to sign in to your bank's website and check for possible bank maintenance.
1. Get first the URL QuickBooks uses to connect.
2. Go to Banking.
3. Select Link account.
Reminder: You don't need to add an account, you just need the listed URL.
4. In the search box, find your bank and click it.
6. Copy the URL for your bank.
5. Sign in to your bank or credit card's website using the copied URL.
Once signed in, it's a good indicator that the issue isn't major. Then check the following things:
1. Check if there are messages, notifications, or alerts in your account.
2. Find out if there are display issues as you navigate the website. This prevents QuickBooks from syncing and downloading transactions.
3. Check if there are announcements about new security requirements on your bank's website.
4. If everything looks good, go back to Quickbooks. Then click Banking and select Update.
