Well, not so much missing, just the button was not pointing to the right place.
This has been corrected. Not sure about you guys, but these days my Firefox browser seems to do nothing when you press the button. It has actually downloaded the pdf file to your “Downloads” folder.
To view, open Windows Explorer and search for the “Downloads” folder, look in the folder for the file “Tealgram-no24”. Double click this to open. If it does not open, you may need to download and install the free Adobe PDF Reader.
