Hey Juan,
Secrets Unlocked episodes here: https://www.tvmaze.com/shows/46670/secrets-unlocked/episodes.
I corrected the old episode order to the new order in my chart below. "The Pharaoh in the Suburbs" always aired on June 15, 2020, at 20:30. But at one point, Smithsonian Channel listed it incorrectly airing May 4, 2020, between Ep 17 "Egypt's Lost City" and Ep 19 (old order) "Riddle of Petra." TVDB still mistakenly lists all three on May 4, 2020. All 30 episodes aired for 30 minutes each at 20:00 and 20:30 on these airdates. I watched them all.
Smithsonian wasn't its usual helpful self with this series. Two or three times, it scheduled one episode but aired another. With several TVmazers making updates, corrections were made except for this one issue. I think shifting this many episode numbers requires explaining. My chart seemed the best way to illustrate this. I'm sorry it took so long for me to fix it. Thanks as always!
Joe
