Hi Andy, thank you for sharing these additional details. I completely understand how frustrating it can be to manually keep presets in sync across Lightroom, Lightroom Classic, and ACR, especially when updating or creating new ones.
At this point, importing/exporting is the only option, and we understand how cumbersome that can be when you’re updating or creating new presets frequently. I’d strongly recommend creating a feature request here: https://adobe.ly/44Mihsj.
This is the best way to get visibility from the product team. Other users can also upvote your request. The team actively monitors these posts when prioritizing future improvements.
Regarding the two issues you mentioned:
• Duplicate imports: You’re right! Lightroom currently doesn’t flag duplicates during import, which can lead to multiple versions of the same preset. Create another feature request or include this in the one you're going to create for Preset Sync across all 3 apps.
• The import stops working, which is not expected behavior. Could you share your Lightroom version and OS details and, if possible, a quick screen recording? This will help us reproduce the issue and log it for the team.
Thanks for bringing this up!
Best,
Anshul Saini
