I'm having a couple of problems with youtube but I'll settle for asking about this one.
When I finish watching a video and select another one to watch it just goes back to the original one. It doesn't matter whether I'm signed in or not. This just started about a week ago.
It only happens on my laptop. No problem on my phone or tablet.
I'm still perplexed by the inbox. On my YouTube app on my old tablet, there was an inbox option where I could see replies to my comment and suchlike. On my new tablet, it's completely missing, and I've no idea why.
I clear the cache regularly(ish).
I select another video by either clicking one that is 'on show' or by entering a title in the search bar. Either way I have the same problem. I do have a favourites file but there is not much in it and it's not used much.
