I since me and Google broke up and me and DDG are kind of like an item now, I have been exploring all of DDG's capabilities lately. I clicked on region and set it for my country. But when I tried to re-set it back to "no region" in advanced settings and on the results page, neither one takes. Clicking the little X next to the region toggle switch just reloads the results page and still has my country selected.
Probably just a charming DDG quirk I haven't figured out yet but it would be nice to know to make the "no region" selection stick.
At the very least, just letting know the DDG staff this option is acting up.
