Sent start request thru App - Said it started, it did not... almost killed battery

Question

The app has worked both hot and cold for the last 6 months no issues.

I replaced my 12v battery as it had been 5 years on Friday.  I drove good distances afterwards, and I also remote started more than once since then.

This morning I remote started thru app, it said vehicle started, but it never showed the headlights etc come on.  I've been using the app to monitor voltage (because I knew my 12v was weak this winter before I replaced it) - So I noticed I started at 12.6.  After issuing remote start I dropped quickly to 12.2, then got the alert in the app of 11.7.  By the time I got to the car it was 11.1.  The car was NOT running, just ignition was on.

I hit the brake.  Then pressed the brake and started manually and everything is working normally now.

Any ideas on what caused this?

In addition - I accidently left my trunk open last week - the car app never alerted me (though I just found and saw that there is a setting for that).
