Update ruined app – Mass Text Message Review

The update from Apple has ruined this app. Please fix where we can send messages to at least 150 clients at once like we use to. Who cares if they use iMessage or not... Please make this app work again. I had rice,cotton, soybean, and corn farmers in different groups and gave updates on crops as needed. I can't do this now... Please fix....
