Downloads seem to be working — given the current restrictions of no downloading of tv shows (only seasons and episodes) and no option to download the next X unwatched items.
Which version of PMS do you have installed on that Windows 8 machine?
The new Plex app on mobile requires a recent version of PMS. I’m not sure Windows 8 is supporting that newer version of PMS (given Windows 8 itself has been out of support by Microsoft since early 2023)
Edit: found it… Windows 8 only supports versions of PMS older than version 1.32.0 which was released 2 years ago. The current public release of PMS is version 1.41.6.
The new mobile apps require PMS version 1.41.2.
