Aaaaaand the issue is fixed: your YouTube homepage should be back to a grid view – not the list view! Thanks for your patience while we worked to resolve this.https://twitter.com/TeamYouTube/status/1189934443856687104 …
Thanks for the tag – Stories is still in beta and may not be available to all channels over 10K subs yet. If your channel becomes eligible, you'll be notified in the YouTube app. Hope this helps clarify!
