When I use the back button in some cases I am getting an old version of the website, instead of loading the page version I started with. I can reintroduce this almost without failure on cnn.com: - from the index choose an article - then go back - the version of yesterday's homepage shows up (yesterday's news) - note by "yesterday" I'm just saying old, it really does not appear to be a fixed time. I also see this on nytimes.com sometimes, but not always. This only happens in my Android version, I do not have this problem in the desktop version. I hope this was clear & the steps to reproduce the issue were sufficient.
