Every database just register the dates as it is displayed on the Originally Available. Converting it to any other standard, UK or French requires some work and honestly that is time spent on something that is not necessary at least at the moment.
If that’s the case, shouldn’t it show “2021-08-07” in both locations? The fact that “Originally Available” is in yyyy-mm-dd format whereas the title is in m/d/y format surely shows that Plex is converting the date to a different standard. If it matched the “Originally Available” format, that would be fine.
Thank you – that set me on the right track. In my server settings, the language was set to “English”. I changed it to “English (UK)”, and now the dates are displaying as I wanted them to.
