Hi minoils and JANECCC1,
I appreciate you both reaching out here. Welcome! BMO is one of the banks that have recently switched to OAuth, to improve online banking for QuickBooks Online customers. In the past you were able to download up to 90-days of historical transactions, now some financial institutions will let you download up to two years of transaction history. It's important that you update your QuickBooks Online connection and I'd be happy to provide more information so you can complete your banking goals as soon as possible!
First and foremost, I recommend clearing cache on your browser. If you've received an email from your bank, follow this guide to update your connection. Otherwise, I suggest disconnecting the account and then reconnect it to QuickBooks Online. When reconnecting, use 'Bank of Montreal Canada-Business(Loans and Investments)'.
If you require additional assistance, please contact us. With your consent, our Customer Care team can work with virtually, and ensure you're back to business as soon as possible!
