I'm currently 56+ hours over my daily playtime despite only having started Sims 4 about 2 hours ago xD
For me the notification pops up every about 10 minutes or so and seems to like to jump about one to 2 hours each time.
Also the notification sometimes doesn't pop up for weeks or months, until it suddenly does again with no indication as to why. I have no playtime limit set, just tracking my overall playtime, but even then my playtime for the past 5 days is only at 25 hours, so I have no idea where it's taking these hours from.
Maybe it's instead falsely tracking the time the EA App is running and using this as playtime? That would line up with the weekly use of my laptop more than my actual playtime. I have the app always running in the background for convenience, it opens automatically at start-up. I'll disable it for now and report back if I find any changes! ^^
