I would request some change in how often you get reminders for an upcoming event on the companion app.
I select my events in advance so while warming up sometimes up to a hour before the time. But the reminder will start popping up 30 min before the event, (this is stil ok) but then it keep coming up every few min.
I would suggest if you snooze the reminder it will remind you every 10 min or again 5 min before the event start, in the last 5 min it can remind you more often.
