Hi
In the editor, I find the preview widths for mobile and tablet to be unhelpful since they are 360px and 780px respectively and therefore don’t match the GP break points of 768px and 1024px.
From your response above, I appreciate that this is a WordPress thing not a GP thing. I’ve tried googling for some way to alter the settings for this Gutenberg preview control – with no success. Do you happen to know of a way to change this?
thanks as ever!
