hi, in the last couple products ive added to my product list on my store ive noticed that the variant picker wont show on the product page and if i reload the web page it will show it but like only for a sec then it will be gone again and ive activated the variant picker on my store as well btw
this the product page
https://duostore.org/collections/hot-sale/products/creative-led-night-light-note-board
Hello @maxxivit 
I checked and can see the app GLO Color Swatch hides the variants. So you should check that app setting, or disable it completely.
Hope that helps!
Hi thanks a lot for taking your time and having a look on my store, yes it was the globo colour swatch app and I found out I had to sync now every time I add a new product to my store so then the variant same rules apply and show
Glad I can help. Hope you all the best!
