I use Quicken on a Windows PC in Canada. It's a subscription based product.
In the past week I have noticed that none of my accounts from Scotiabank are updating properly and I am getting a CC-505 error. It was working flawlessly in the past.
It connects to the account as I am getting a notification sent to my iPhone to ask if it is me trying to login which is a standard security feature from Scotia Bank to ensure you are aware that someone is logging into the account.
