I'm using Chrome, signed into QBO in a incognito session and received the same error trying to disconnect.  One background piece of info, this online 'bank' was sold so if it needs to connect to disconnect, that can't happen.  Edward Jones sold their credit card services to US Bank.  I have no pending CC transactions so when I get the US Bank credentials I'll add that but don't I need to keep the existing Edward Jones account for history or can that be deleted?

Thanks,

Rick
