After the update of Samsung Galaxy Note 10 Plus to Android 12, one bug is observed that, whenever i edit a video with applying a song, the video get muted (song removed) while uploading (whatsapp status) or sharing video to anybody.
Dude i had finding the issue on many website and observed that the issue is raising in many users after Mar-Apr 2021 update. May be the issue due to the software update. The issue may be resolved in next update.
