ScrollTo Plugin issues with ios update

[tallwhitey]

My site was experiencing issues using the scrollTo plugin with the window element on ios devices after i installed the latest update 11.1 (iphone 6s plus). 

In order to determine if it was conflicting with anything else, I instead looked for previous codepens. And confirmed that the one linked is also not working on ios devices but does on desktop and android.

Is this a known bug again? or any workarounds for this in the meantime?

Sorry to hear there is a problem. 

We are looking into it. 

Give us a little time please. 

 

Thank you.

I've spent hours researching this and every indication is that it's a bug in iOS Safari that only applies to iframes. Here's proof:

Notice that if you view that in an iframe on iOS, it doesn't work. It's supposed to scroll to 400px from the top after 1 second. There is no GSAP involvement whatsoever. It's pure JS. 

 

Thus far, I can't figure out any workarounds to force iOS Safari to work. I have submitted a bug report to Apple, so hopefully they'll get it resolved. Sorry for the bad news.
