I have create an advergame for a brand, but I have a big problem!
When I use it from Facebook or Instagram app (this brand is doing advertising with the HTML5 game) with an iPhone, sometime it not in the correct size. It seems That the app does not recognize the dimension of the game and it is like super zoomed (see the picture below).
I do not Know how to solve it and I do not understand where is the problem.
Anyone know why? How can I solve it?
My idea: I think that the viewport meta tag in the HTML file is not read in the correct way, but I really don’t know if it is correct and what to do!
