Mobile Phone Image keeps moving when I adjust position in desktop view & vice versa.

Yes, as the title says. I get it where I want it in desktop view, then I go into mobile optimisation & adjust it there & when I go back to desktop, it's moved. Surely they're allowed to be different?

Re: The screenshots below...

1) Bottle image positioned correctly (with red glow touching line across top).

2) Red glow bleeding off left edge in mobile view.

3) Bottle adjusted in mobile view.

4) Bottle has now moved in Desktop view (with red glow no longer hitting the horizontal line & leaves chopped off at the bottom).

If I adjust the desktop image to be like screenshot 1, then mobile view changes to screenshot 2.

When you say that you are adjusting the image, what changes are you making?

The content of the page and content of the blocks (including focal point and alignment) will have the same settings on both desktop and mobile. The only thing you can change between desktop and mobile is the size and position of the blocks in the grid, the content stays the same.

Ah, well I have both set to fill & I'm changing the vertical alignment of one (using that little white circle icon) & the horizontal alignment on the other, so that will be it.

I shall look into it & find a crop that can be used on both.
