(sorry I am a subscriber of chess.com and get only this format, I could cut and paste the PGN directly here if this is preferred)

Thanks. Yes, pasting the PGN is preferred, since I just use your chess.com link to copy the PGN from there, and then import it into https://lichess.org/analysis to verify and get the resulting FEN.
