Hi @LollyNino_C, I've reached out to Discover & they are not performing any maintenance.  I am able to setup a test company & connect a new account to the Discover Card Express Web bank feed without issue.  This would indicate to me that things are fine on the Discover Card side of things.

Do you have any other suggestions, aside from contacting customer care?  They've never resolved an issue for me and just point me to the same support articles I've already found myself & ask me to run a rebuild again.

I suspect the problem is that Discover turned off their old feed on 6/30 and my QB account was still connected.  This is preventing QB from deactivating the bank feed.
