Since upgrading to Catalina I've noticed some major inconsistencies with icloud sync'ing, most noticeably with photos and notes.
Photos on my MBP has updated several times today but still does not show the latest photos and videos taken on my phone. When I look at photos on the icloud website, that too has some images/videos on my phone but not others. My phone has been connected to WiFi at home for days now.
Certainly under Mojave and iOS 12 things were a lot better...a lot smoother, but with iOS 13 and Catalina, it's terrible.
