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.
Hi, thanks for the fix, can confirm its back to grid view now. Some feedback for you: it might be okay UI for phones, but its absolutely unworkable for a PC. Please don't roll this change out to desktop users. Cheers!
