Recently I have noticed that the next_episode result is null on the Watched Progress using the API. This seems to have happened in the last couple of weeks.
For example, Stranger Things. I have watched all aired episodes, and season 5 episode 1 has an air date. Using the Watched Progress API, the next_episode is null. This returned a result a few weeks ago. This only seems to affect shows that have not yet aired episodes 1 of their new season.
Do you have any guidance on this?
