Opponent timed out, but won the game

In the following blitz game, my opponent ran out of time in a hopeless position, but I've come back to find out that I lost the game on time. The Android app notified me that I won the game as well. 

Can someone from support help me understand what happened at the end of the game?

The link says that you were the one who ran out of time. 

If you want the staff to take a look, write an email to support. (Support@chess.com) They do not often read the forum.

I don't suppose you have a screenshot of the Android app notice? You should mention that as a bug.

 Thanks @notmtwain. I'll email support

My guess is that the app may have given the notification after your last pawn move. However, it was really disconnected from the server and had never received white's last Rh7+ move. The times stamps on that game show you went from 43 seconds to losing on time, very indicative to being disconnected.
