> [...] and it pretty much just works.

I beg to differ. Last time I had to use PowerPoint (granted, that was ~3 years ago), math on the slides broke when you touched it with a client that wasn't of the same type as the one that initially put it there. So you would need to use either the web app or the desktop app to edit it, but you couldn't switch between them. Since we were working on the slides with multiple people you also never knew what you had to use if someone else wrote that part initially.

could it be a font issue?

If I remember correctly I had created the math parts with the windows PowerPoint app and it was shown more or less correctly in the web app, until I double clicked on it and it completely broke; something like it being a singular element that wasn't editable at all when it should have been a longer expression, I don't remember the details. But I am pretty sure it wasn't just a font issue.
