Presets disappeared

Hello @Kali M. 

Did you recently re-install that app?  The reason I asked is because I see that you had probably been using the free version of Lightroom, which does not have cloud storage backup for presets or photos.  So uninstalling the free app would also delete all the images, presets and other data that were stored inside the app.  (I notice that after your post above you did subscribe, but this would not help recover any files or presets that were removed if the free version of the app was deleted.)

Is it possible you have an iTunes or iCloud backup of your device, made at a time when Lightroom still had your images and presets inside the app.  If so, restoring that backup onto you device would restore the previous instance of Lightroom along with your lost photos and presets.  And then, as long as that Lightroom uses the same emaild address which just subscribed, your older stuff should simply sync to LR cloud backup.  Other then this, I'm afraid there's no way to recover your lost items.
