This makes a little more sense than the article's demo, but I still only perceive two flashes, even with the audio. Maybe it's also environmental...

For what it’s worth I’m viewing it fullscreen on a phone.

The version with three beeps and two flashes is a different illusion. This one is supposed to have an actual third flash and no beeps.

Nope, it has only two flashes in reality :)

If, like me, you are perceiving three when focusing on the + then the illusion is working. When I focus on the line where the flashes appear then I can clearly see there are actually only two flashes.

No, the article is a different illusion. Three flashes.

I recorded it and slowed it for you

And just in case I was going mad I checked the frames of the gif. There are 50 frames. Frame 15 has the left dot, 17 and 18 have the right dot.
