Hopefully the NVC and US Consulate in Rio de Janeiro will work to reduce the waiting time to schedule an interview.
It is taking about 130 days after DQ to receive an IL.
Have you tried in your health center where do you live? Ask for your vaccination records, It worked for me.
Also there is information on this website:

@chrisbonatto there are another cases that 7 to 8 days after the first or second 60 days notice email, they receive an email scheduling the interview. So You are very close to receive it๐๐
