Every time I start Quicken my computer downloads at least 45MB, maybe more.. I don't know why. (My QDF file is about 65MB, which is a separate problem.) I don't have Quicken backup; I keep all backups on my own separate disk partition, so what is the problem that requires Quicken to get all that data? This happens every time. And as you can see, my network bandwidth isn't all that huge; so what's going on?
(Windows 10, Quicken R63.21, but it's been going on for weeks if not months (startup has always been slow, but I started paying attention only lately, so I believe months).
