Joining the chorus of people PPO'd at QB/Inuit over this Chase issue, which popped up for me suddenly last week - unable to download Chase transactions using the Bank Feed and unable to reset it, first being told it DID work:

Then it immediately failed:

Called Chase - who sent me to QB - and HOURS of talking with support people - including so-called supervisors - most of whom were clueless and kept repeating that Chase changed the connections (yes, back in Sept which I "updated" then and it all worked - sort of -  for 2 months) - until finally claiming with Chase I could only use the "Web Connect" downloads (one for each Chase account) which of course is NOT TRUE.

I have QB Desktop 2022 R6_27 - the latest update - one company, one user (Admin - Owner).  No "fix" mentioned here works for me and my PC is not blocking Intuit/QB/Chase, etc. in any fashion. 

Even when the post-Sept 27 "Express Web Connect" connected and downloaded - it would take several repeat downloads to get (almost) all transactions - as others have mentioned - sometimes duplicates and some transactions NEVER downloaded. 

Pathetic.
