This has happened for a long time. If I see a video on my main suggestion page, I always right click and open link in new tab. But occasionally it will also open it in my main YouTube home suggestion page. The main problem with this is if I click the back button (not the home button) to return. It doesn’t return to where I was, well actually it tries to give that impression, for example if I was half way down the suggestion page… it returns half way down the suggestion page. Except all the suggestions are new, so I’m not picking up where I left off. Meaning there may be many videos above where I now am, that I might be interested in. It’s the same thing If I return after I restart the browser or the computer.
If you’re going to reload all new suggestions… just return to the top of the page, because you’re not resuming, where I was!
