I have DuckDuckGo installed as my default search engine in Safari on both my iPhone 6 and iPad mini 2 (both iOS 9.1). I also have it installed on my PC, but on my PC I'm able to customise the settings whereas on my Apple devices the customisations don't save and apply.
For example, if I use my device to click on the
burger icon in DuckDuckGo search results > Advanced Settings > Advertisements, and change from
OFF, then click
Save and Exit, the settings don't save and the search results still display ads. Is this a known bug, and if so, is there a solution for it?
