I often set reminders in Google Calendar on the Android version, but when I check my Calendar on the web, those reminders are nowhere to be found. Even though this article states it should have been possible in 2016: https://blog.google/products/calendar/reminders-come-to-google-calendar-on-the-web/
I also checked the web version of Google Keep, since Calendar reminders seem to have a strange symbiotic relation with Google Keep notes, but my reminders aren't there either.
Maybe asking for a way to add reminders is too much, but I'd really like to at least be able to view my reminders without relying on a specific device.
Edit - My "creation dialog" also looks different from Walt's: there is no input for selecting reminder:
