I had a customer reach out because they could not add my products to their cart.
I asked a few friends to check out my store on the app and they ran into the same issue. Desktop works just fine, but mobile fails to add to cart.
I was able to add all your items to my cart.
I just added to cart on both desktop and on the app with no issue, Usually when there is an issue like that wit the app it's because they are using an outdated version of the app.
