Saving presets onto Lightroom on IOS

[#1]

1. Help! I bought presets from a website that instructs to download and when I go to Dropbox to save it by clicking “more” where Lightroom should show up but it’s not.  How do I get these presets on Lightroom?

Hi, what format is the Preset?

If it's a DNG (image file) then you just import this into Lightroom Mobile and Create Preset from the settings that have been applied to the image. Otherwise, it would have to be imported in Lightroom Desktop (if you have a subscription thay includes it) and will sync to Mobile from there.

The problem is how do I import the DNG file into Lightroom?
