Bests & Worsts Reviews from Amazon

I've been using this product for over s year now and absolutely love it. Have it set up for auto delivery each month. Something is definitely off with this latest batch. I noticed that the consistency is much coarser and doesn't dissolve as much. I've never had this happen in the past. Has the formula changed? If so please change it back to its original formula. The consistency was much smoother and would dissolve quickly in both hot and cold beverages. What went wrong???
