This is the second time this has happened. My bank is a manually maintained account as they aren't on the network to sync with Simplifi. When I enter a credit card payment, I get the notification that I'm adding a manual unmatched transaction, which I accept.
However, I log in later, and the transactions are gone. I've checked the transactions list, and yes, they are gone, and yes, I have no filters active.
