Instagram doesn't have an in-built feature to check your Instagram Reel watch history, but there are some workarounds that could help.One way to view Instagram Reels you have previously watched is to check the posts you have liked in the Your Activity section on your profile page.Another method is to check your Saved posts where you must switch to the Reels tab to view the saved reels.You can also view your Instagram Reels watch history on the desktop version of Instagram.To extract the links of Instagram Reels you have watched previously, you can request and manually download your Instagram data.Apart from these options, you can also use social media websites such as Facebook or Google search to re-watch Instagram Reels you have seen before.You can find reels you interacted with, such as those you liked, in Your Activity > Interactions > Likes.If you remember the creator who shared the Instagram reel video, you can check out their other social media handles to view the Reels.Unfortunately, there's no option to see what reels you've watched on Instagram if you haven't interacted with them in some way.If the Reels video you uploaded is missing, you should update the Instagram app and check whether you have deleted it.
