I uploaded a Pdf on yumpu.com, apparently successfully. It was only during the upload process that I learned of the adverts to be put on the ePaper in the free version.
I got the API and it was accepted by the WordPress plugin.
However, the plugin did not list my Pdf from yumpu.com.
I uploaded the same Pdf directly into the plugin, but it still did not list anything.
I went to delete my yumpu.com account, but could not find a route to do so because it demanded a password, and I had signed up via Google and I so had never set a password.
The yumpu.com profile change-password option demands the old password first, even though I am logged in.
The login password reset email's link simply goes to the yumpu.com home page, so I cannot set a password. Ah, that is while I am logged in! It does invite a new password if I open the email's link in a private browser window... that's a fail.
Even now, with a password set, the delete-profile option fails: "Ooh no, something went wrong !". How can I delete my yumpu profile?
