I appreciate the detailed information you shared regarding account confirmation when changing your payment method for App Transactions in QuickBooks Online (QBO), Mastrong.

To address the issue, we can try some troubleshooting steps to determine if it's browser-related:

• Refresh the current page (Ctrl+R or Command+R)
• Sign out, then sign in again to your QBO account
• Use a different browser
• Use a private or incognito window:
  • • Google Chrome: Ctrl + Shift + N
    • Mozilla Firefox: Ctrl + Shift + P
    • Microsoft Edge: Ctrl + Shift + N
    • Safari: Command + Shift + N

Once done, try updating your payment method.

Same problem! This has frustrated me for weeks now! How can they let this go unresolved for SO long?! When I click save, these 3 black dots popup and then nothing. We pay way to much for this software for this type of issue. I have tried all the suggestions... logging out, clearing cache, incognito, different browsers, PC, mobile device. Nothing works. Here's what I get after trying to confirm the account and clicking the Save button.

Thank you for reaching out, Shortbg, and for taking the time to explain the issue in detail. We truly appreciate your patience and effort as you work to resolve this matter.
