I cannot find the original presets that I paid for many many months ago. I should have these for life. Now the only presets I see are then asking me to upgrade to the Premium version. I paid for the app in the first place. Where are the "clean" (etc) presets? Please help!
The Presets and Profiles buttons moved locations on the Edit toolbar. Tap Presets, and switch from Premium to the Library tab, and scroll down until you see User Presets--your presets should be there. All your existing presets should still exist, unless you deleted the free version of the Lightroom mobile app (the free app does not sync anything to cloud storage/backup).
