“Auto” button setting does not apply to all selected photos when “Sync / Auto” is enabled.

Hi @claudedeschenes,

Thanks for reporting this. We’re investigating a similar issue with Auto Sync, and I’d like to confirm whether you’re seeing the same behavior.

Could you let us know:

• Approximately how many photos are selected when this happens?

• After enabling Auto Sync and clicking Auto, are the Auto settings applied only to the active photo, or do they initially appear on all selected photos and then disappear/reset?

• Does the behavior change for selected photos that are outside the currently visible portion of the Filmstrip?

• Please also share Help > System Info > Copy.
  
  

If possible, a short screen recording showing the selection, Auto Sync enabled, and what happens after clicking Auto would also be very helpful.

Thanks,
Anshul Saini

Also, are you in Library or Develop? (The Auto button and Auto Sync are available in both modules.)

Mac? Windows? Version numbers? I cannot reproduce this on my Mac running Lightroom Classic 15.5.1 in MacOS Tahoe 26.6.2. All selected photos are automatically (and individually) adjusted when I click the ‘Auto’ button with ‘Auto Sync’ enabled.
