Why the pdf files can't be downloaded recently?

If there are any issues with downloading, you can submit a Ticket with the pdf link, so we can check or fix the download link.

There are no issues detected right now, maybe some network issues suffered, but you can try to click download again without the Points requested.

I also just downloaded one, no issue. Did you check your Points were enough? Check "My Wallet" page.
