Hi, Debi. I understand how important it is to have your bank transactions syncing smoothly to keep your books connected and stay accurate. Since you've already cleared your browser and restarted your phone, let’s look at the next steps to get your connection finalized right away.
Before we proceed, could you tell us which bank you are trying to connect to your company file? Providing more details will help us resolve your inquiry more effectively.
The reason you’re unable to connect and save a bank connection is often a communication error between your bank's security system and QuickBooks Online. Even after clearing your browser cache, a pop-up blocker or an outdated setting might still be preventing the final save command from completing.
Since clearing your browser didn't work, using a private window is the best way to ensure that extensions like the ad-blockers are not interfering with the process. For your reference, please see this page. Troubleshoot browser problems for QuickBooks Online and Intuit websites.
