So My STEP exam was scheduled on the 30th, today I recieved an email from prometric that they are cancelling my exam due to covid 19. This is my 2nd extension so what do I do now? Do I have to re-register all the paperwork for the exam?! Has this affected anyone else!?

It happened to me too! my test day was 30th as well, 2nd extension. According to ECFMG(if you are an IMG), they said they would re-assign eligibility period til the end of the year, but I have not received any official email or announcement about it.
