I've noticed this on various sites, but I'll use YouTube as an example. I'm sitting on my YouTube 'home' page and I see a set of 'suggestions'. I click on one of the suggested vids and watch it. Afterward, I hit the 'back' button in the browser (there is not an embedded back button in the app). Sometimes hitting the 'back' button takes me back to the same YouTube page with my suggested videos and I can watch another. Other times, hitting the 'back' button causes a new page to load and I now have a new set of suggested videos displayed. This behavior is not consistent - sometime the page load occurs, other times the same page appears. I cannot detect a pattern to this. What's annoying about this is that there may have been more than one thing I wanted to view on the initial 'suggested videos' section of the original page displayed. However, after watching one of the vids and hitting the 'back' button, if a new page loads, I now no longer have access to those other suggested vids I wanted to watch. As I noted earlier, I've seen this behavior in other apps too. I don't know if this is the right place to ask about this, or if it's a browser thing at all, I'm just trying to understand what's causing this behavior and figure out if there's anyway for me to mitigate it.
