Huh, I thought the hole in the ozone was a success story for decisive environmental action and that it was "fixed"

It is actually getting better, it just takes time.

In fact, according to the above Wikipedia article it was in a great spot in 2019 and then a volcano erupted:

In 2019, the ozone hole was at its smallest in the previous thirty years, due to the warmer polar stratosphere weakening the polar vortex. In September 2023, the Antarctic ozone hole was one of the largest on record, at 26 million square kilometers. The anomalously large ozone loss may have been a result of the 2022 Tonga volcanic eruption.
