Thank you for posting here in the Community. I'm here to share some information about the bank feeds in QuickBooks.
Currently, our Banking feature is working as designed, and we're not receiving any reported issues with it in general. Users can connect and maintain the connection with the system. The connection of your accounts in QuickBooks depends on your bank's website.
Any scheduled maintenance or interruptions will affect the connectivity from our end. These will lead to linked accounts getting disconnected automatically.
If issues like this happen, I recommend logging in to your bank's website. Try to check if you're able to access your account and review the settings related to syncing third-party apps.
In case the problem persists, I suggest sharing adding more details about the name of your bank. You can add additional information by leaving a comment below.
