I appreciate the efforts you've put into the issue you've encountered when trying to select a payment method in your customer's account, @bbmhayes.
Let's perform some basic troubleshooting steps to help you fix this. You can log in to your QBO account using a private browser. This way, you can double-check the accurate setup on your account.
You can use these shortcut keys on your keyboard to access incognito mode:
- Safari: Control + Option + P
- Google Chrome: Press Ctrl + Shift + N
- Firefox or Internet Explorer: Ctrl + Shift + P
If that works fine using a private browser, go back to your original browser and clear its cache so the system can start fresh. Also, using a different supported browser can help us dig deep into the root cause of this unexpected behavior.
