Vue, fetch get and Iphone conflict?

Question

Vue.js

Sending data to the server using the get method in this way

fetch(`/product/${id}/delete`, {
method: 'get'
})

does not work on Iphone-Safari. When the button is clicked, nothing happens. The button itself is pressed and the styles change. No send to server. On a computer with Win10 everything works. Also post sending works on iphone axios.post
How to send a get with Vue in order to work on iphone? Or remake under axios.post?
UPDATE
Updating the iPhone solved the problem. What does not affect the question. the problem was, which means it may occur to users.
