Downloading issue – Pro Editor - Video Maker for FaceBook & Youtube Review

I have been using this app for a long time now and so far I have had not one issue. Recently , I ran into trouble involving the downloading process for a YouTube video . All video formats seem to download perfectly in M4A format but I came across an error that is changing the format completely . This change is a “ Videoplayback.Unkown”. This will not open the YouTube video I’ve downloaded . I am investigating further to see if it might be the video from YouTube itself but again, I’ve never had this issue until today. Please , fix this . Without this being fixed , the app is well useless for downloading videos from YouTube . Thanks for reading .
