Recent iOS, update calendar issues

And the iOS update I have the opposite problem with my calendar. I delete them daily as I crossed them off my to-do list very satisfying end of day routine in my calendar is full of all my previous dates/to-do. This is not the first time this happened also, the new Calendar function really sucks. I think I’ll look into an alternative be nice if they ask the user base if they would like the update to include such a change it’s horrible.
