Hi nxt_kwa,
We see that you have already reviewed How to get your Apple Music Replay - Apple Support which is the best article for this particular issue.
Just to confirm, did you complete the steps under "If you don't see Replay" which includes the steps for turning on Use Listening History for all devices that you own? We wanted to ensure this step is complete, to ensure Apple Music Replay has access to all the data it needs to generate that for you.
If so, let's reach out to support so they can look into this further with you using: Official Apple Support
Cheers.
