I've been on iOS 8.2 for awhile and I haven't noticed that problem. I just checked again and no issue. I use chrome though to surf the web not safari.
Just did a quick test on safari too and it doesn't look like there's any issue. Do you have your history or cookies erase on closing the browser? That would cause an issue. Other than that though, I don't know.
One change I did notice recently though on my laptop is that if you logout and try to log back in you get taken to the main rivals page rather than a scarletnation page.
