When someone shares a video with you, it lands in your Shared with me view. Shares are temporary by default — here's how to keep the ones you want and clear the ones you don't.
Shares expire on their own
Most shares are a "look at this now" moment, so the person sharing usually lets them expire — after a day, a week (the default), a month, or never. When a share expires it simply disappears from your list; you don't have to do anything, and the sender isn't told.
Opening a shared video marks it as seen automatically, which clears its "new" badge — there's no separate "mark as read" button.
Hide what you don't need
Not interested? Hide a share to remove it from your list, or use Hide all to clear everything in one tap. Hiding is silent — the sender is never notified — and it doesn't end your access early; the share still lapses on its own. Hidden shares stay reachable under the Hidden view until they expire.
Keep what you want for good
If you want a video no matter what the owner does later, save your own copy.
