Hi there @arslan410!
Don here from Shopify.
Thanks for letting us know about the issue you're experiencing at the moment.
If you can share a link to your store here, I can check this out from my side to see if I can reproduce this behaviour.
Would you have set your store up more recently or has it been running online for a while?
Let me know if you've made any changes to your store's domain or settings recently so we can check this out together.
