Simple way to remove all images automatically added from Camera Roll

[dmsf]

Like many others, I accidentally ticked the box for "automatically sync images from camera roll" so that all the junk in there- memes and screenshots and pictures of loyalty barcodes and stuff listed on Ebay- partially synced to Creative Cloud. 

I have turned it off on all of my devices but the junk remains in lightroom. Now that it's off is there a way to sort by source so I can see all the images automatically added from camera roll and delete them? Or, better yet, is there an option to delete images that were automatically added when the sync option is disabled? Currently thery're all mixed in with the photos I want to keep and it looks like I'll have to sift through hundereds of photos to remove the junk.

How do you remove camera roll images that automatically got uploaded?

You can select them all and delete them. Easiest way is in Grid view, go to ... menu > Select Photos.  Tap each of the photos you want to delete, or drag your finger over to select multiple. Then delete down the bottom. You might want to use the funnel icon to filter by camera to narrow it down to just ones captured on that device first, although it would still include ones you'd imported intentionally.
