How to remove LrC synced photo from web?

[shikamu]

I have a collection in Lightroom Classic 13.1 that has been synced so that there is an album on my https://lightroom.adobe.com page.  Yesterday I accidentally added a photo to that collection in LrC and it got synced to the album on the web.  When I realized my mistake I removed the photo from the collection, but the photo is still in the album on the web.  In LrC syncing is turned on.

Why is this photo still in the web album even though it is not in the corresponding LrC collection anymore?

How can I get the album and collection to be in sync so that the album has only the photos in the collection?

use a web browser to navigate to the following locations. at each location there are several folders/link to check.:

https://assets.adobe.com

https://lightroom.adobe.com

https://documentcloud.adobe.com

https://spark.adobe.com

if you delete anything from any of these locations, check for a deleted folder where your file(s) was (were) moved. if you want to clear space you must delete files in the deleted folder. the used storage shown at each of those four sites (when totaled), should match the space shown used by your cc files.
