I believe you should receive BTS as part of the 11/05 sharedrop, as long as you owned them on November 5th. There was also a much earlier snapshot back in February I believe. One think you may want to check is to see if you have the most recent versions of the BTS client. I believe that v0.4.27.2 is the first to allow access to your vested balance from the 11/5 snapshot, but I still haven't tried it out myself. Hope this helps.
