Nothing inflates, I thought I was doing something wrong and it turns out it was the yeast's fault. Whatever I tried to do, it doesn't inflate

Honestly, if I hadn't seen it with my own eyes, I wouldn't believe it. I put the dough in the refrigerator for 24 hours along with a sachet as well because I had experienced it in the past and it didn't rise. I threw away the remaining 2 as they were completely useless.

Unfortunately, due to this specific yeast, the loukoumades did not rise. I threw away the other two bags of the package!

I am trying to make pizza dough by trying various recipes. The dough never rises and when I bake it, it has a terrible taste. I realized that the yeast is to blame. I put it in the water and it never foams, which I understand is because the yeast is dead. I made sure that all the other parameters are fine, for example, the water is at the right temperature, etc. I have been trying for so long to understand what is going wrong, and seeing the other reviews, I realize that the common factor is that I always use this specific product. Even though it is well before the expiration date and I store it in a suitable place, it never works. I have tried around 15 packets. ALWAYS the same problem.

Loukoumades, same recipe for 20 years...the dough didn't rise, they turned out tight like rubber. Something has changed in the quality of the yeast, it can't be explained otherwise.
