Hello @accounts-singapo,
In QuickBooks Online, you can manually update your bank account to reconnect your account and download your transactions. I'll show you how.
- Go to Transactions.
- Select Banking.
- Click Update.
But if updating your account doesn't change anything, it is recommended to check first with your bank's website for updates before reconnecting your bank account in QuickBooks.
In the same manner, here's an article you can read to learn more about reconnecting your bank account online: What to do if you get a bank error or can't download transactions in QuickBooks Online.
On top of that, I've also included this reference helpful with the steps needed in reviewing your bank transactions: Categorise and match online bank transactions in QuickBooks Online.
Don't hesitate to post again here if you have other questions or concerns with QuickBooks tasks and navigations. I'm always around happy to help. Take care and stay safe!
