Np prices and Payment methods on mobile checkout

Hi,

If the total amount is zero, then the HikaShop checkout will proceed without displaying any payment method selection. That's normal.
It's the same for the shipping method selection. It won't appear if it is not necessary to ship the products in the cart.

From what I understand of your screenshot, like looks like you created a product called "kadobon", and that product has a characteristic with values which are prices. And you've added variants to this product for these values. However, you didn't configure anything in the "prices" area of either the main product, or the individual variants of the product.
So they all have no price. That's why the total amount is zero in the cart.
So you want to edit each variant, under the "variants" tab of the product edit form, and in the "prices" area, click on the "+" icon to add a price with the value corresponding to the variant you're editing. Validate the price, save the variant, and repeat for each variant.
HikaShop will then see these prices and the total amount won't be zero anymore.
