Why does the 'ñ' sound always get me? Any tips for mouth placement?

I’m a perfectionist when it comes to sounds and I’ve been recording myself daily to practice the palatal nasal 'ñ'. I can differentiate it when listening to native speakers, but when I play back my own voice, it just sounds like a standard 'n'. Are there any specific tongue-muscle exercises or common Wolof pronunciation traps I should be aware of to make this sound more natural?
