Baby dislikes formula

I’m 6 months pp and my milk supply is not able to keep up with my baby’s needs anymore. We’ve been exclusively feeding breastmilk by bottle for most of her life. I attempted to feed her 2oz of formula today (Enfamil Enspire, since it’s supposed to be most similar to breastmilk) and she reaaaally dislike it- grimacing face, whining, dribbling milk from her mouth. I know she was still hungry because I gave her only a fraction of her normal bottle amount right before trying the formula. I also warmed the bottle like I usually do.

Has this happened to anyone else before?? Does anyone have any suggestions or tips? Trying not to feel bad as it is and her reaction just made me so sad 😩
