Audio asset included in the app is not working

I’m producing an new app. I’ve changed my asset audio from Mark1 to Matthew1 and changed Mark1 to download the audio to the app.

When I produced the new app about 3 weeks ago and tried it the audio asset for Matthew1 was included in the app and if you clicked the play button for Matthew 1 it would play immediately. In the mean time I’ve changed computers and copied over my SAB data to my new laptop.

How can I check if the asset is there and how can I make it work. All the other chapters in the New Testament and the old testament which we have published works fine (they download the audio). The only one which doesn’t work is the asset in Matthew1
