Product showing currently unavailable


I’ m having hard time with the listing of my product.

So i have an GTIN exemption, my brand is validated but somehow after adding my first product, my Amazon product page won’t show the buying options like my customers can’t buy it, and this message displays " currently unavailable " i do not know what to do more.

Help please

Note: i am taking care of the shipping not amazon.

Is your inventory actually showing as available in Seller Central? Is the listing ‘active’?
