i'm also having problems with chase online checking and quickbooks online, however not with overlapping transactions, but rather with omitting transactions? Has this happened to anyone else? I probably would never have noticed except I searched my QB transactions for a particularly large payment I made to have my work truck worked on and when I couldn't find it, I noticed that there was a large gap in transaction dates of  20 + days which I knew was not accurate as I use that card multiple times  daily. So I promptly logged into my Chase account and downloaded the statement for that period and sure enough there was about 20 transactions listed on my Chase monthly statement that did not get automatically transferred to my QB online, and these transactions were in the middle of the statement period, meaning QB had transactions listed both before and after the missing dates that were all part of the same statement period from my bank? I additionally found more missing transactions over a shorter gap in missing dates of about 7 days on the following month's statement? Wtf is up with that?
