“Before cancelling your subscription, you must agree to the following”
The wording on that notice is atrocious, but it seems like the actual behavior isn’t horrible. In reality, they seem to be trying to convey:If you cancel your subscription, any content which you still have in your account will revert to the privacy options of the free plan. If you don’t want some content to be public, delete it before making this change.Whoever at Prezi manages this UI should definitely clean it up to actually say that, but the behavior itself doesn’t seem crazy to me.
