Cannot play .m4a file in safari recorded in iOS app.

Question

I have an application in which I need to record audio and upload it to the server and send the file link to the user.

Now when I try to open mail on Mac or Windows, it works fine and I hear a sound. But when I try to open the link on the iPhone or iPad, it will not play it.

While I had a demo application for the project, and when I try to do the same thing, it worked.

Please help me.

Thanks in advance.
