I think I figured that out, might be the bgm is too long and too large to load. I cut it in half and tested on an old phone, it seems fine.
I can test it if you want, just upload it and I'll give it a shot. You can just upload the new version of the bgm, I knox how to copy-paste
I will upload the fixed version together with some new content within 1-2 month.
Ok nice. Thanks for letting me now.
