I have recently switched to the Brooklyn theme, and discovered an issue with the Instagram in-app browser. I know other brands pages with the same theme that have the same exact issue, and have by process of elimination determined the problem is caused by the Slideshow.
Steps to reproduce:
1) Open Instagram on iOS, go to @banger.supply (my page)
2) Click the website link in bio which will pop up the in-app browser
3) Scroll up and down slightly
