During the time period 1/31-2/4 I have missing transactions from:
Avidia Bank, Bank of America, Capital One, and Citibank
There is just a hole in the transaction records, because I have transactions from after that time period for these accounts, and my online balances (in Quicken) appear to be correct.
I saw at least one announcement for missing transactions for a different institution, but since this appears to be affecting multiple institutions I would have expected to see something..
