To be clear, NOYB allows 60 days after notification for removal (instead of 30 allowed by the law) before complaining to the national data protection agency and even then agencies rarely give out serious fines if you are ready to comply and did not grossly misuse the data, at least in Sweden: https://www.enforcementtracker.com.
