What are the requirements for music for the watch

[mimimix]

I downloaded m4a audio from YouTube and converted it to mp3 (via ffmpeg ) , but Zepp application ( version 7.10.1 ) doesn't show it in explorer. ( other tracks are visible )
I will attach audio information below.

Hi, I'm here to understand the full usage scenario, are you transferring music files to your watch device via zepp?

[mimimix]

yes

[mimimix]

I'll attach an archive with an .mp3 file that doesn't work
music.zip

Hi, we recommend submitting user feedback in the Zepp App, and remember to check Device Logs and Zepp Logs!

Here is the operation path
