I make bread but with yeast that I bring from the US. No success with yeast bought here. To be fresh, even if it is powder yeast, it needs to be keep in the refrigerator, and the water temp is very important. BUT I use the 5-minute bread recipe with some of adjustments on the flour side (more flour or less water), otherwise the heat and humidity make don't help. Better yet, use whole-wheat flour instead of white. I used this same recipe for pizza as well as a regular pizza dough recipe and they both work well.
