When was the last time every team scored in the championship?

As of my last update in October 2023, the last time every team scored in a championship game was during the 2020 UEFA European Championship (Euro 2020), which took place in 2021 due to the COVID-19 pandemic. In the group stage, all teams managed to score at least once in their respective matches. For specific details about different championships or leagues, please clarify which one you are referring to.
