Hi. The deodorant doesn't roll up. I've ordered a replace my one as well but both have the same issue. Any recommendations?

Try putting it in a warm place or in front of a heater - even just hold it in warm hands for a minute or so. That always worked for me, and then once it started rolling up, I never had issues with it getting stuck again.

Is this the exact same formula as Pit Paste?

Yes, it is the same formula as the most recent Primal Pit Paste formula

Does this product cause Oil stain on clothing armpit?

It stains my husband’s shirts black, but not mine nor my daughters. I’m not sure why though. My guess is sweat or over application. It is the best natural deodorant that I’ve found.
