One report was enough, you did not need to submit reports for every other episode.

Archives of the "VOD" section on the show's page on the SBS website don't display the episodes but this archive of the "About" section from Dec. 2017 says there are 32 episodes.

Didn't know how to treat it with the reports. Makes sense.

Seems the original SBS release has 32 episodes, with most titles spanning 2 episodes. The SBS site is live and shows that: https://programs.sbs.co.kr/drama/wyws/mainThe Netflix and Viki releases have 16 episodes and I could mostly find these web releases. Viki is still live: https://www.viki.com/tv/33538c-while-you-were-sleeping#episodes Wikipedia also has the 16 episodes and matches the titles that exist for the 32 episodes: https://en.wikipedia.org/wiki/While_You_Were_Sleeping_(2017_TV_series)

Not sure what the rule is in that case. I would think it make more sense to go with the higher quality Web release order as default and offer the original aired order as option if possible. Would probably give the best outcome for metadata users through the media servers.

The current SBS website has 32 episodes but I don't know if it also had 32 episodes back in 2017. But seeing as the episodes were added by a moderator and the 2017 archive of the "About" section also mentioned 32 episodes, it looks like it also had 32 episodes back in 2017.

Seeing as the 32 episode version looks to be the original one, that's the one to follow and the one that should be used on TMDB.
