Has anyone else out there who has an Instant Pot had success with using it as a slow cooker instead of a pressure cooker? The existence of recipes suggests this should be possible, but the one time we tried it, even on high the contents of the pot never got near a temperature hot enough to actually cook anything - it only achieved bacteria-fest warmth, or what would have been a bacteria-fest had we actually allowed it to sit there for hours before deciding "screw it, this is going in the oven". Did we maybe get a dud? It works as expected in other modes, so it's not a failure of the heating element, but could still possibly be a failure of control circuitry or something. (It's academic as it's far out of warranty now, even if we had wanted to hassle with support at the time, but I'm curious.)
