I have a problem in modifying the video. When I add a musical sound to it, save it and send it back via WhatsApp, the music disappears from the video!!
This seems to be WA issue coz I am regularly doing such stuff on my S21Ultra and there are no issues at all. Try to send same video by quick share feature or by bluetooth to other device and check if same problem persists. If not then update the WA and clear it's cache.
Hi there, this happens when WhatsApp tries to compress the video to reduce the file size. Try using the send as document feature and let us know whether the issue persists.
