As said above, I have the setting off on laptop, but my presets still wont sync to mobile. I am using the Lightroom that is not classic on laptop, with Lighroom CC on my phone, running IOS 10. I have tried creating a preset using an image, but the option does not show up. Only the copy/paste settings option shows up. On the mobile app it says, "Synced and Backed Up."
Are you really running iOS 10? That is a very old system! iOS is currently at version 14.5.1. If you are running such an old OS, then you may be running a very old version of Lightroom as well, and that may be the reason that presets won't show: this may be a version that didn't support presets yet. What version of Lightroom on the phone do you have?
