While editing in Lightroom Classic v12.4 with Camera Raw v15.4 (latest versions of both) and NOT using Lr mobile on any devices, multiple snapshots are appearing in Lightroom Classic. All of the snapshots are labeled "From Lr mobile." I have recently shared some collections, but the images I am editing are not shared.
As I understand it, "From Lr Mobile" in the history panel in normal when editing on Lr Mobile. But the snapshots are not. The issue occurred on a small number of images from the same timeframe, so I'm guessing that even though Lr Mobile was not in use, it was running in the background on one of our devices. That said, I don't even see a way to create snapshots in Lr Mobile.
Highlighting the snapshots on an image shows different edits, so they do seem to be actual snapshots taken at different times.
