Thank you. Have you recieved your BVL? Can you see your visa details? If yes, I strongly advice that you reach out to the visa offices in Nigeria. I did and I recieved the PPR within 24 hours.
Our timeline is very similar. I applied for my brother in December 2022 as well. BVL on April 27, visa details are showing on the tracker. I pray we get OPR soon.
