Adobe Rush mobile app won't export

I edited a 40 second clip on the mobile app (using a brand new Samsung galaxy and latest version of the app) and every time the export reaches 40%, it crashes and causes my phone to reboot. There are no graphics or effects applied. I have no other apps running and also have more than enough storage on my phone. I even tried a smaller 10 second sequence and it does the same. I can only seem to export one clip at a time, which defeats the purpose of editing a sequence. Please help.
