I am currently Using Windows 11, 23H2. So, I have set the lock screen via DF to a singular image. Yet somehow, due to Windows Spotlight being persistent I guess, the lockscreen keeps auto-changing to a seeming Windows package wallpaper. All without my feedback or consent.

Is this perhaps an issue with how the DF wallpaper clocks work?
I am lost, baffled, and annoyed at this issue.

EDIT: I double-checked, and "Allow DisplayFusion to manage the Windows Lock Screen" is enabled.

It appears to have been caused by a setting from AcuWeather that I originally turned on without thought. I noticed a pattern with the lock screen wallpapers that is being swapped, in that they were suspiciously seasonal.

It is a learning experience on my part, but I wonder what can be done with DF settings to take into account external apps like that.
