I've been finding for a while (maybe since iOS 7) that if I switch from Safari to, say, Mail for a while, then back to Safari, the website will refresh and often logs out of the site I was logged into. This has got far worse with iOS 10, to the point that when I return to Safari, the screen is white for a while till it restores the page. This often logs the page out, which is what I'd expect if I actually closed the browser.
I've also seen it when just changing tabs, which never happened prior to iOS 10.
Anyone else? I'm curious to know if this is happening on the latest iPads, which have more RAM than my iPad 4.
