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.
I thought that was over
The ozone hole is mostly repaired, because we stopped using CFC’s.

Yup much like with acid rain Reagan and George HW Bush stepped up environmental regulations to confront the problem.
As most of the problem was due to America’s use of CFC’s it was their issue to solve.
