When performing my daily OSU this morning, I noticed that my accounts at American Express, Ally Bank, Chase, Bank of America and Citi Cards have not been updated since April 4th. This info comes from the OSU Summary Window, which shows the last update for each FI.
I then Reset one of my accounts in each of the FI's, which took me through the Reauthorizaton Process again. During this process , the missing transactions were downloaded.
This has happened before with AMEX,3 times so far with BofA and also with TD Bank.
