I’m doing this just now and it’s miserable. New Siri is still miles behind. Currently having to jump through natural language hoops to get Siri to add an alert to a calendar event and when I finally get it to confirm it did the job, it doesn’t actually do it- just claims it did.Having now seen some more demos of people using it, I am actually excited about trying New Siri for this.
I assume (and hope) the natural language entry will be refined as the betas go on.
But according to what they say and what I've seen, I should finally just be able to open my calendar and tell Siri to add and adjust the things I see there.
