I use my Instant Pot in pretty much exactly this way, but have never had lumpy yogurt, so maybe something else?

That's good to know, thank ou. Maybe it's my starter culture. I had been using yogurt from Dannon or a Skyrr.

Try (if you can find it!) Stoneyfield plain yogurt, not their Greek-style. It tastes great, and I have a 100% success rate with that as a starter. Good luck!
