Can't zoom in to magazines in News on a MacBook

It looks like the zoom functionality is disabled in the News app on Mac -- and it pretty much makes reading magazines impossible. The usual keyboard shortcuts don't work either.

It also looks like there are a bunch of old questions saying the same thing with no resolution. Does anyone have a workaround?

On a side note, it doesn't look like News is available as a topic in these forums, so I just picked something else.
