i am unable to hear the music on my store/mobile
[Note: the feature that allows developers to reply to reviews has only been available since March 2019, that's the reason for the late reply]
After being contacted by the merchant, we quickly checked that the music was playing perfectly in this store on all modern browsers and sent a video recording of their store showing the music playing.
Unfortunately, the merchant never updated their review with this information.
Anyone can check that the app music works smoothly by visiting our demo store, which can be found in this app listing page.
