I think it’s more accurate to say the problem is mostly solved and its on track to being repaired rather than mostly repaired.

Antarctic ozone hole:
2000: 28.3 million sq km (largest recorded).
2020: 24 million sq km.
2024: 20 million sq km (approx 3x size of usa).

Global ozone levels will return to 1980 levels around 2040.
Arctic ozone will recover by 2045 (currently around 1 million sq km).
Antarctic ozone hole will fully recover by 2066.
