Photos deleted from Lightroom Mobile (cloud) are not automatically deleted from Lightroom Classic

[Maxim Gurkin]

Hi all. In Lightroom Classic I have two catalogs: All Photographs and All Synced Photographs. When I delete a cloud photo in Lightroom Classic it is deleted from both catalogs and from the cloud (I can see it in the trash bin in Lightroom Mobile). However, when I delete a photo in the cloud using Lightroom Mobile photo is only deleted from the All Synced Photographs catalog in Lightroom Classic but still remains in the All Photographs Catalog. That is pretty annoying as I need to delete the local copy in Lightroom Classic each time I delete a photo from the cloud. Is there any way to set up Lightroom Classic completely delete all local copies when a file is deleted in the cloud?

What you are describing is correct behavior. 

Once a file makes to the Lightroom Classic Catalog it is 'safe' - meaning that the mobile ecosystem clients can no longer affect its existence in the Lightroom Classic Catalog. Disk-based file operations are reserved for Classic.

Thanks for the confirmation that it is "as designed" behavior.

Do it the other way round.....delete the image from LrClassic, and that will also delete it from the Cloud.

If there is a wish to select within Lr Mobile which images should be deleted - these could be instead flagged in some way (or given a particular rating). After this flag or rating has synced back down to the image seen in LrClassic, it can be used there as an aid to deletion. That gets rid in one go of the local image file, its importation to the Catalog, and its presence in the cloud ecosystem.

Thanks for the suggestion, that can definitely simplify catalog management. I also found another mechanism - make a diff between all photos and synced photos through Select All / Inverse Selection operations, but it looks like a hack.

It definitely works, but I pretty often clean up the catalog using an iPad while waiting in a queue or using any sort of transportation. @richardplondon flag suggestion can help here.
