Hey @Leong_Kin_Foong1,
I moved this post to it’s own thread so we can focus just on this and leave the other resolved.
First, may I ask that you please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Is your Airport able to play non MQA content from TIDAL? Are any other endpoints exhibiting this behavior? Are you receiving any error messages when trying to play this content?
Can you share a screenshot of Device Setup for your Airport Express?
Thanks,
Dylan
