You're most welcome, @Silver Bullet.

I understand that it would be time-consuming to manually enter those transactions especially if you have a lot of missing entries. However, at this time we don't have a specific turn-around time yet when this will be available. 

Once the issue is resolved for missing transactions, those will eventually be downloaded into QuickBooks. Since you've already called our Online support, I believe your account is already in the list of affected users. Once the issue with AMEX is resolved, our support will immediately notify you through your email.

I'll also be on the lookout for this investigation and give an update on this thread as well if this is already available. 

Please let me know if you need anything else. Best regards.
