Yes - people outside the USA who use that USA link, then log in with their usual details, will with an ounce of luck be able to subscribe to Pro Tools and get the new DNA tools.
Some people who already have a Pro Tools subscription are saying they can't see the new tools - perhaps they need to log out, then log in again.
Some people are saying they still have coloured dots, not coloured squares - I have dots on my 1st page, then squares for matches!
You need a 'proper' Ancestry subscription/membership in order to be able to purchase Pro Tools (AncestryDNA Plus is not sufficient).
