Last month, I was prompted to update my American Express account due to changes to the way Quicken connected, and that appeared to have been OK. But since then, I'm getting "Your last online session was not completed" messages both when Quicken opens and closes. I've run validate and super-validate, and I've confirmed that all of my accounts appear to be updating properly in the OSU Summary, and all of my transactions have been accepted. Everything appears to be fine, other than this persistent message.
I've de-activated the AmEx account, but the issue persists. I've reinstalled Quicken, and moved my data file as well, as I started to have issues with Quicken locking my data file and being unable to open it on subsequent attempts.
Any other advice to try to get rid of this annoying message?
