"off" smell (beyond normal tanginess)
That watery liquid is whey — it's completely normal and safe. It separates naturally over time. You can either stir it back in (it contains protein and nutrients) or pour it off if you prefer thicker yogurt.
Yogurt is one of the more forgiving dairy products when it comes to dates. The live cultures help protect it. Use your senses: if it looks normal and smells normal (yogurt is supposed to smell a little tangy), it's almost certainly safe. When in doubt, a small taste will tell you immediately if something's off.
