If your YouTube homepage is showing videos in a list view (instead of a grid) this is not an intentional change and we're working to fix it! Thanks for all of your reports, and we'll share another update when the issue is resolved.
I had a problem with the views, my views fell over 70% from day to night and all my videos were good, and from what I learned from the support you were doing tests, a lot of people were complaining too, that would be the solution to this problem? I hope so kkk
