Here's How You Can Do It
In the Amazon homepage, click on "Browsing History," then select "View and Edit" browsing history. Any items one has viewed, as well as any Prime Video selections, should appear in this list in chronological order, starting with most recent.
If you select the carrot next to "Manage history," you're given a few options: You can choose to wipe out your entire history by selecting "Remove all items," or you can select individual items to delete.
