I did what you did @Joey-Phx - downloaded a QBO file and imported it, and got a few new transactions and some duplicates, and I did see the notice you're talking about.

I deleted the Web Connect connection to set it up again, and it worked like I said, but now this date error.

This is a situation I think where the problem is the lack of standards, and the lack of an overarching player to drive adoption of those standards. The banks and Intuit and Quicken (and other players in the financial software space) need to come up with something like Zelle, an organization and a standard for interchange of data that all of the players can agree to and participate in. Until that happens, Everybody is always going to be scraping websites and every small change in the code of the site is a potential stopper for data interchange. This needs to work much more like Office 365 where I can grant enterprise applications permissions on my tenant to do useful things. There’s definitely a good model for dealing with this, but we’ve just got to get everybody on board.
