We have same issue with my brother F2A priority date 2019. We got letter from embassy in Philippines saying we are ready to process his visa so we go ahead and do all the interview preparations they told us to do. Only to find out on the day of interview appointment that he missed the cut off date and he is in included in retrogression.I did not get a letter from embassy or NVC about this changes so they sent my brother home not being interviewed and was told to re-schedule and come back and always watch online the visa bulletin changes and wait for the priority date to be current before making visa interview appointment at the embassy.Right now month Aug they are processing priority date year 2017 below so our priority date 2019, went 3 yrs back from July 2023 since our priority date became current and we missed it, so that means very slow and waiting game again until our priority date will be current.😔😔😔
