Hi, Grestorn
This workaround with "country or region" also worked for me. thanks, dude!
I've tried to solved for a couple of days without sucess, even creating a support ticket with enpass and then dealing with microsoft support (they tried to buy the app at their side without sucess and then told me there was a glitch in the microsoft store and I should try to buy at a later time. haha what a useless advise).
