Thanks for the quick reply.
I did not know you could add voice over as a third layer so that is good to know. But if I try to add my music on the voiceover layer it won't let me add any music or sounds effects on this third layer so it feels like this layer is strictly voiceover layer.
This leaves my original issue unresolved since I need more than 2 layers for music. Hence, I posted a feature suggestion for your product team on the provided link.
Thanks for your help.
Thanks for posting the feature suggestion, @Tehmina359044755yrt. Until the feature is available in Adobe Express, you can try merging/layering the audio files using other Adobe applications, such as Adobe Audition, Premiere Pro, or After Effects. Using these apps, you can create a single audio file from multiple and then utilize that.
