Hello,
On an old version of Safari in iPhone (12.1) the Add to Cart tap is working great, if you tap the button just one time, the item enters the Cart Ok. Video here:

But on the latest versions of Safari, I have to tap 2 times in order to get the item to the Cart. Video:

Looking forward.
Thanks!
