Quality Product - Unfortunately too slow to be useful. Very often, when you answer a call on the Nest doorbell, the delivery person is likely to have walked away by the time you get a live feed and begin speaking. This is key to it's functionality & it's a real shame as everything else is pretty good with the Nest doorbell. **UPDATE** 11/03/22 Furthermore, trying to scroll back through & view past events is impossible. I've missed all callers whilst away because of this apps poor performance
