Part of the problem is the QB support team is in the Phillipines and they don't fully grasp what is happening due to a language barrier, I get so frustrated with this.  It is NOT Chase bank, there are way too many people that are having this same issue.  The only thing that worked for me was to dissconnect my bank feed and reconnect it and now it's working again.  I also deleted cookies and used the self fix tools in quickbooks under help. 

Unfortunately their support team can't help, they just want to text you a list of instructions instead of jumping in to help resolve the issue.  I feel for everyone that can't get theirs working!!!
