We discussed this at work today (physicist here). Essentially the related paper(s) are based on data fits that could indicate functioning, although really shitty, qubits.

Looking at the fitted data I’d wager they might just as well have fitted noise. Really not convincing at all.

Most of academia had already abandoned majorana qubits, so this claim by Microsoft really caught people off guard - and extraordinary claims require extraordinary evidence - something Microsoft lacks.
