I’ve been trying to add certain media as watched, primarily shorts and films I’ve seen that are released between the dates provided in the title. I can add them to my library, I can give them a rating, I can add them to lists. But I can’t add them as watched unless I give them dates later than their official release date.
(I can add them with a specific (often much) later date, or an unknown date, but not their release date)
That makes sense as the likelihood of you having actually watched them on release date is incredible slim. This seems like a situation where you should be using unknown date rather than release date as the date of when you watched it is unknown
