I appreciate your effort in clearing the cache or cookies and switching to other browsers to check if it's a webpage issue, @morgran1234. I can also see the urgency of fixing the Search function and having the ability to customize customer balance reports. Worry no more, I'll share another way of contacting our Support Team directly.
Upon checking my resources here, there's a new investigation report (INV-88393) about using the Search option in Customer List. With this, you need to connect with our Support Team. They will add you to the list of affected users to receive notifications about the progress and fixes available.
Since the Community space is a public forum, we cannot give a contact number directly. It is to protect you from any harm. You can visit this page instead and scroll down to the Can't get signed in? section: QuickBooks Online Support. From there, you'll see the contact number you can use to call us directly.
Once everything's settled, check out these references to learn more tips about personalizing reports and then saving their current customization to save time:
Feel free to let me know how the call goes. I'd like to ensure that the Search function and customize buttons work perfectly on your end. Take care.
