There are too many Mayas on this site, i saw the title and thought it was one i'd done lol!!
I have the opposite problem with my Maya, she is a little piggie, eats everything in site, and has learned how to get IN (yes, literally!) the "dog-proof" bin to get leftovers lol I've even been sending pics to her breeders asking if she is too fat as im paranoid lol I have her on a bit of a diet now…
I feed Maya a mostly raw diet, but she has a meal a day of dry complete puppy food. She eats anything, but LOVES the raw. If you're trying to get your Maya more interested in eating then i'd buy some cheap mince or chicken and cook that for her, i bet she'd eat that no problems 😃
