MB Fuel One Whey Protein Powder (Old MRP) , 4.4 lb Rich Chocolate

I?ve been using Fuel One Whey Max for almost a year because it was affordable and good quality. But now the price has increased, and the quality seems different too. I?m using the Mango flavour, and the taste and mixability are not like the previous batches. Even after mixing with water, I?m getting a powdery, rice-flour-like residue. I know this product very well, so this feels unusual. I?m concerned about the quality and may get it lab-tested. Please look into this batch.
