I set my region and language setting using the bookmark settings like so …
Trouble is when click on the flag to change the region nothing much seems to change.
If I search for obama I get telegraph.co.uk, en.wikipedia.org and biograph.com as the first three links for the region set to UK and USA.
If I switch to https://duckduckgo.com/
I get the same links for the UK but I get barackobama.com, en.wikipedia.org and whitehouse.gov for USA.
It would seem the bookmark settings in links is messing up the flag region settings.
