I'm having trouble getting the function ConcaveHullMesh to work. As far as I can make out from what I can see in my User Portal, I'm running the latest version of Mathematica (13.0.1.0). Even the two Basic examples in the Online Documentation Center don't work: when I evaluate these expressions I just get back the input. One possibility is that the latest version of Mathematica isn't appearing in my User Portal. I say this because the Documentation Centre has a page titled Summary of New Features in 13.1. But, as mentioned above, I'm running 13.0.1.0 which must surely be an earlier version? I'm somewhat confused and any advice/suggestions would be much appreciated.
