Download problems with Discover

It feels like every other month I have an issue. Sometimes it's double items, sometimes it's a bad balance. I've been a user for over 30 years and I have just about reached the end of my rope with this. I'm going to have to untangle this mess manually again. It just feels like the only way to avoid the issue is to download every day, so that I can more easily identify the problem when it happens, or just abandon downloads. Not happy with Quicken.
