Anyway, since nothing has changed hardware or software wise, and the fact that the Mk4S with MMMU3 is working perfectly (even as I type this), then I don't believe it's a printer issue, but more likely a Prusa Connect issue.

I now see that this is no longer the case and was wondering if it's an intentional omission, or if there is a bug somewhere.
