I had some success in the first ballot for (the eventually postponed) EURO 2020. Then, at various points over the following months, I received emails from UEFA with 'personal offers'. These emails invited me to log in to the ticket portal, where tickets for a small number of matches were available for me to buy immediately - up to 4 tickets per match. I was frequently offered the matches in Baku, but I was also given the opportunity to buy tickets for games in other cities, including Glasgow and Dublin. So, if you took part in the first ballot, and even if you were partially successful, I'd say keep an eye on your email inbox in the weeks and months ahead. You may well receive 'personal offers' to order tickets for some of the 'less attractive' matches ... but possibly some of the more attractive matches too!
