Xfinity doorbell

Hi. I’m new to the Xfinity doorbell and have a few questions. 

1. Is it normal not to see a recording after an event? I’m seeing the still picture in the notification but no recording.

2. Should I be able to view the doorbell camera on my touchscreen and the Xfinity home app?

3. Are there other rules besides those listed in the Xfinity app and where can they be found? 

Thanks.
