Both USAA and American Express are converting to Express Web Connect+. From an email notification:
Quicken has partnered with USAA for a faster, more reliable connection.
We are putting the finishing touches on the new connection now, but when we finish, you can expect fewer download errors and more reliable serviceall through a more secure connection.
You dont need to do anything now. We'll start notifying you within the next 60 days when it's time to make the switch.
