I don't post here really at all, (just occasionally browse around visa time!) as nothing more helpful to add than the great advice already posted by other users. But Hopefully this will put your mind at ease. We applied for 2nd flr(m) on 2nd Feb, biometrics on 22nd Feb and just received the BRP this morning. Looks like it was granted on the 19th march. Was worried that there would be a delay but seems like it was submitted in time and wasn't affected. Hopefully you hear back in the next few days if you're a few days behind us. Keep well.
