mp3 audio plays on my device and simulator but some users have issue

Hi I just released an app which is live. i have a strange issue: while the audio files in the app play fine on my device, but some users are unable to hear. One friend said it played yesterday but not today. Any idea why? The files are mp3, I see them in Build Phase, and in the project obviously. Here's the audio view code, thank you!

import AVFoundation

struct MeditationView: View {
    @State private var player: AVAudioPlayer?
    @State private var isPlaying = false
    @State private var selectedMeditation: String?
    var isiPad = UIDevice.current.userInterfaceIdiom == .pad
    let columns = [GridItem(.flexible()),GridItem(.flexible())]
    
    let tracks = ["Intro":"intro.mp3",
                  "Peace" : "mysoundbath1.mp3",
                  "Serenity" : "mysoundbath2.mp3",
                  "Relax" : "mysoundbath3.mp3"]
    
    var body: some View {
        VStack{
            VStack{
                VStack{
                    Image("dhvani").resizable().aspectRatio(contentMode: .fit)
                        .frame(width: 120)
                    Text("Enter the world of Dhvani soundbath sessions, click lotus icon to play.")
                        .font(.custom("Times New Roman", size: 20))
                        .lineLimit(nil)
