### Description of your *issue*, suggested solution and other information

I am unable to download this video (https://www.vlive.tv/video/54099) that I have already paid for. 
I think the ONLY_APP message is because it only allow users to download the video using the app but even so, it does not download the actual video as users can only play the video using the app. It would be really great if it is possible to have to download this video in my computer because it always take forever to buffer this video in the website. 


Thank you.
