Baby Brezza

I just did the formula test on my baby brezza and it was off by 1.5/2 scoops!! I am so heartbroken. I have reached out to the company and have not heard back from them yet! Has this happened to any other moms? If so how long did it take your baby to gain back weight after you stopped using it?

I should note that I do everything by the book! I wash and wipe down everything after 4 bottles, I take it apart every 2 weeks and give it a good wash (let air dry before putting back together) it is on the correct powder setting! I have even tried other ones while doing the formula test to see if it would help and it did nothing!! Ugh.
