Supposedly I have the latest version of Chrome running on my Mac (78.0.3904.108) but the Kindle Cloud Reader app says I don't.  It says this version doesn't support the latest Chrome Extension format.  Consequently I can't download anything.  OTOH, I can Download in Safari but your app can't see it.
