Multiple times in the past week I've noticed that after downloading transactions from two of my credit cards, transactions are missing (one is with a Barclay's US credit card using EWC, the other with an AMEX card using EWC+). In each instance I've picked this up because the account doesn't reconcile and I have to go back through the transaction list on the credit card website to find the missing transactions. What I've noticed in this process is that the missing transactions have all had the same amount as a recent previous transaction for the account. So I suspect that this is an instance where error checking to avoid downloading duplicate transactions isn't working correctly. Obviously this is a HUGE issue for me - it is extremely tedious to go back through my credit card transactions in Quicken and compare them to the online list to find what is missing.
Apologies if this has been posted elsewhere, I didn't find the identical information in other posts.
