When I click the three dots in front of the category name, I see the "Turn on reminders" in the context menu. Then I click on it to enable the reminders. The context menu text changes to "Turn off reminders", apparently meaning that the reminders for that event type are now enabled.
However if I refresh the page now and open the context menu for that event type, I see the "Turn on reminders" again. So, I can't figure out if the reminders are actually on or off.
