I can confirm it's a game bug, not a connection or phone issue. The following things happen almost every day, no matter if I'm on wifi or cellular. Basically when you completed a run after the first login of the day or a few hours of rest, the game crashes when attempting to show the score screen. Then you load the game up and it gives the message that the score wasn't displayed so it attempts to show it again, but this time it loses the connection and does a soft reset.

The good thing though is that you don't lose any rewards you got. You just won't see them. I assume that Mystery Boxes are determined in advanced when the run is over, so they should be included as well. We can only hope for a fix from the devs.
