Hello there, Pedro. The issue where the customer field appears blank or unselectable during a payment is usually tied to your browser's stored cache. This unusual behavior can be fix by following a few troubleshooting steps.
First, let's refresh your browser to clear out any temporary data. Afterward, log out and sign back into your QBO account to establish a new connection.
If the issue persists, I recommend logging in your QBO account using a private browser or incognito mode. Since this mode ignores existing cache files, it is an effective way to see if the browser is the source of the issue. Alternatively, you might try using a different supported browser, such as Google Chrome, for a more stable QuickBooks experience.
Once signed in, attempt to receive a payment again to confirm that your customers are visible and selectable.
If you have more questions, feel free to ask. We're here to assist.
