Help I need HD Drams

Hello, these couple of weeks I have problem downloading drams from Facebook into my mobile in HD. Previously it was easy but now whenever I download an episode it's in 360p, I am using an app called (HD Facebook Downloader) but now it doesn't work fully, I downloaded another one called HD Video I succeeded in HD videos but apparently it is without an audio pls help me dear friends 

P. S. My dramas are from groups not a general page

Can you link to a random public facebook video? I can't say I have tried downloading from there recently but I would imagine you could get an .mp4 from your web browser's developer tools.

I don't get what u mean
