Hers is my take.
Blighty left the EU Jan 2020..bang! along comes Covid 19. I didn't travel anywhere outside of my EU country during that time.
Blighty leaving the EU meant that if i had left my country i would not have been allowed back in again as a British passport holder.
I decided to become a citizen of my EU country (took two weeks) and i can now travel to any schengen country without a passport.
And of course being dual nationality i won't have any bother getting into Blighty. Best of both worlds
