I need help! It takes so much data to play?!

So i've played this game about 4 months i guess and using cellular network is just fine that only took about 50mb per day, but not the recent 4 days until now! Can you imagine it? That now this game took my cell nets around 0.95GB in TWO DAYS!!

I do realize these day they just added ads to the factory that finish your goods instantly but i guess that thing that won't cost this much. Everytime they came up i close the game and restart the it. I also have disabled usage data sharing and usage data for effect downloads.

Is there's something changes so big that it took my cell nets this way? If this thing keeps up then i might quit and won't come back.

Please i need help
