All,
This has been resolved and verified using the current [as of 7 July 2019] versions of Firefox, IE, Edge, and Chrome on Windows 10. Please let me know if you are still having issues (particularly using iOS or Linux).
FWIW, the cause seems to have been a css error pushing the ‘download’ button far off screen to the right (perhaps due to a recent plugin update).
Apologies for the inconvenience.
-Scott
