Great game, but I've lost my score twice – 2 For 2 Review

This game is great and addicting, but twice now I've opened the app to having my score completely wiped out. The first time it happened, my high score was over 10 million before it forced me to start a new game. Just today after the app updated, it kept the current board of numbered dots where I left off but once again my score of 2 million has been erased and replaced with 0. Very frustrating
