When dissolving natural organic yeast in water, is it supposed to bubble?
Based on your comments, it sounds like you're adding the dry yeast powder to water. The yeast typically won't bubble or do much of anything else at this phase.

Yeast are microscopic organisms that produce gas by consuming sugars and excreting carbon dioxide. This requires that they have sugar to eat, which plain water of course doesn't. The main purpose of water is to rehydrate the yeast and revive them from their dried state.

Once you mix the yeast into a dough (which does contain sugars in flour that the yeast can consume) they'll start producing gas, but this isn't a fast process. You may not even see visible bubbles, just the end result as your dough rises over the course of hours.

So there's not yet any indication of problems with your yeast. If you have issues once they're mixed into the dough, there are many skilled bakers here who can provide diagnosis.
