mobile website store categories
On PC if you go to my website store, you are able to view categories. If you go to my store via mobile phone, it only shows view products. Customers are always contacting me, asking if there is anyway to view categories and I have to tell them to tap on "view all products" and that's the only way they can view categories. Is there any way I can get categories to show on mobile? Also, Is there any way I can get a QR Code for my website without having to pay $100.00 a year(qrcodegenerator)?
