Serious Problem

Something really annoying is happening to me. What's happening is whenever I watch something for however long and go back to the home page, it doesn't update. I first thought this was happening because it didn't update across devices, but that was not true after updating properly. I confirmed that it was not the case. The other possibility is that it doesn't update properly. I have to re-enter and update, and then leave. After I do that, it updates properly. Why is this happening, and please fix it. Either way, please fix it.
