No Download Button After veryfying

I’m testing the plugin.

After an email sent to the subscriber with a link like below

https://dapur-uang.com/unduh/?ver=3367285139bfc46d5b3379af4b3be901c37b0d5a

If I click the link, it just redirect me to the page ‘Unduh’ without any button to download.

Is there any step I missed?
