We appreciate you bringing this matter to our attention, a.vi. For the time being, we haven't received official reports from affected users about the Manage consent button not working. This banking functionality issue in QuickBooks Online (QBO) is likely browser-related, so let's work together to troubleshoot and fix this.

Let's start by pulling up your QuickBooks account using a private browser (incognito). Here's how:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)

Once signed in, go to the Banking or Transactions menu to reconfirm your bank consent.

If the Manage consent button functions well, return to your default browser and clear its cache. After that, log out and then log back into your account. This will refresh the system and remove older data that causes viewing and performance issues. 

However, if this matter continues, I'd recommend using other supported browsers. Then, you can contact our Customer Care team for further investigation.

Additionally, we recommend reconciling your accounts every month to keep track of your finances accurately.

Keep in touch if you have additional bank connectivity concerns or issues managing transactions. I'll get back to provide the assistance you need.
