I accidentally uploaded to the wrong Album
Not to worry! If you accidentally uploaded to the wrong album, let your event host know and they will be able to move the photo/video to the correct album.
Hosts can move media from one album to another by navigating to their host dashboard and selecting into 'View event dashboard'. From here select the Media dropdown menu —> Manage Media. As the host, you can bulk select photos/videos and then select 'Move' at the top, then select what album you would like to move the photos to.
