It's back. A year after posting this problem I am getting it again. The last few days I get a zero balance for my Amex HYSA and a valid balance for my Amex credit card. Simplifi also only gives me the pending-balance option not the default bank-balanace option.
The HYSA transactions are correct, but the balance is zero which is not correct.
Is this an annual problem?
