[Ionic v3] Iframe with session lost in old OS

Hello anybody :slight_smile:

I have a real problem, if you help me it would be nice.

I use iframe to show view from website, but for visualize some view i need to be connected in this website.

So i have something like this:

{url to sso} / sso? token = {token} & redirect = {url to view}

I precise, i have token.
And this solution work most of the time, but for the old os (like Iphone 6 ios 11.4) I lost all time the session

The “/ sso” url working with nginx server
