Android version 6.0 and Huawei EMUI V4.1
All google music and all other built-in media player shows track, title etc. I have the Xiialive Pro - but it shows not metadata.

Hello, Same problem I just switched to the new Huawei P9, no metadata info on my Porsche PCM display. Used to work fine on my older HTC M8. Now I get no Track title/name no artist info! Any help in regard would be appreciated.
