I couldn't figure out how to search this, but it's something that keeps happening to me. If I Google something in Safari using the address bar, it will bring up results, I can click on something, and most of the time it works fine. But, sometimes when I try and swap back to the Google results, the page will either go blank or get stuck on the web site page. If I'm several pages deep into a site I can keep swiping back on the site without problem, but when I then the swipe back to Google won't work. Even if I type in my search in the address bar again or refresh it won't work and I have to close the tab and try again. Anyone else?
