Hello !
I noticed that the attribute user-scalable=0 of the viewport meta in the Shopify checkout UI is removing the capability to zoom on certain devices.
As mentioned in this article https://dequeuniversity.com/rules/axe/3.3/meta-viewport, it seems that this is an accessibility issue. People with partial or low vision can’t properly zoom on the native checkout of Shopify. I don’t know if I’m missing something here or if there is a good reason to disable the ability to zoom ?
