No Call from Monitoring when alarm tripped?

A few days ago, while my system was armed away, one of my motion sensors tripped and set off the alarm (my fault, the sensitivity was set to high). I did not have my phone with me so i didn’t see any of the alerts until almost an hour later. I do have professional monitoring enabled. What’s concerning is all three of my emergency contact numbers did not get a call for almost ten minutes from Ring after the alarm triggered, and even then it was only an *automated* call to let me know the alarm had tripped. Police were dispatched several minutes after that, almost 13 minutes from the initial alarm activation. 1. Why did it take 10 minutes to get a call? 2. Why was this call automated? I’d think If it was a a real emergency you’d want a live person asking for your verbal password. 3. Was the delay because the only sensor that tripped was motion, no perimeter (window/door) sensors? Just looking for some clarification if this is expected behavior or a fluke.
