Yes, can you believe Apple's Reminders only allows you to set or change due dates on the mobile app of macOS app side? Seems unbelievable seeing this is a tasks/reminders app, but that's what Apple did for years now. So basically the Apple Reminders app is unusable for me. So the lesson is that your OS provider does not always provide the best application.
Google actually does a pretty good job with Tasks, and it is fully functional across all OS's you will use (until Google shuts it down, of course).

The Google Tasks mobile app now has a tab bar for quickly switching between task lists.
