Great game but... – Pokémon Shuffle Mobile Review

I had this game for about 2 or 3 years. I had a lot of Pokémon, about 95 hearts, and up to around level 300 when for no reason ALL of my progress deleted and now I have to start from the beginning. There needs to be some kind of backup system so this won’t happen.
