Unwatched Video Indicator DISAPPEARED! – YouTube: Watch, Listen, Stream Review

On the Bell notification tab, there used to be a tiny blue indicator symbol to the left of each video icon (denoting a new and unwatched video) from your subscriptions. After the last update, this is now broken and no new videos show an indicator. This makes it tough to keep track of what’s new and what’s been watched already (especially music). Please fix - I’m a long time YouTube Red premium subscriber and this is negatively affecting my experience on the IOS app.
