I know there is a fair amount of discussion around transaction downloads not working, whether credit card or other institutions so I'll share my experience this morning.
Opened Quicken this morning and my Citi VISA Card connection (Express Web Connect+) was no longer there and I did NOT change/deactivate, etc… I was able to add the account again and new transactions downloaded and everything appears A-OK. It did take an unusually long time for the account to complete its process (5 minutes or so).
I'm relatively new to credit card downloads so don't know if this is common or not. Just figured I'd mention it.
