Hello @SkyeMo , Welcome to the Webroot Community,.

Sorry this question might of been overlooked/missed.. For me when using Webroot Mobile Security I open it and in the search bar I looked for Duckduckgo search engine and added it to Webroot Bookmarks. So now when I open Webroot I can search with Duckduckgo.  It's a workaround  but it works for me. 

@SkyeMo  I forgot to mention: Once you add to Bookmarks, open it to where you saved DuckDuckgo and tap the link and it’ll open to the Home page.
