Yes. I was just coming back to say that I had figured this out as well.... that instead of all transactions in our Business credit card account (with 10 credit cards) coming into one credit card account - I now have had to create sub credit card accounts for all 10 credit cards. and yes. there is now no check for previously existing transactions the date range is super important. it's a huge pain in the butt - I'm not sure which date it broke... I think perhaps the 1st of the year ?
It seems like lots and lots of people would be having this issue and it would be important to QB and Chase to fix it.
