video downloading twice in latest mobile app

Everytime i download a video from youtube using savefrom.net android app in my Xiaomi redmi 4, it starts two downloads. This problem is happening after the update. And 1 more thing, the savefrom don't work with (short ) link shared from youtube app.I have to copy the link, open the page in browser then copy the url and paste in the app.Then only i can download the video.Its very frustrating and completely destroys the whole benefit of having an app.Please fix it
