I made an edit from a holiday I made with my friends to Poland yesterday, with the music Milosc w Zakopanem in the file. When i upload this to instagram it only gives me the video, without any sound. I also need more than 90 seconds of the song for the video, so the library isn't really an option for me. Is there a workaround to have the full song under the video? Or is that impossible on instagram
