@TeamYouTube, I use YouTube on Microsoft Edge on my Xbox One, and for the past few days, the thumbnails for videos haven't been showing, just a completely white thumbnail with a turning page icon thing at the top left... Why's this happened and how can it be fixed?
That's odd. You may want to try the troubleshooting steps under 'Xbox error message' section in this article: https://yt.be/help/44WG . If that still doesn't help, send your feedback right away for review: https://yt.be/help/feedback . Hope this gets fixed soon.
