TV show artwork doesn't update as expected

[Rocknol]

Describe the bug

Hello, first of all thanks for the hard work.
So I've had this issue for as long as I can remember. I'm using the PlexKodiConnect add-on path, with basically two Plex libraries: movies and TV shows. When I change movie artwork from Plex(poster or fanart), the same movie is updated on Kodi with the artwork I chose on Plex, within a few seconds. Perfect then. However when I try to do the same thing with TV shows, it's not updated before the scheduled sync, or when I manually sync from PKC options.

To Reproduce

Steps to reproduce the behavior:

1. Change some tv show artwork on Plex
2. Wait for Kodi to show the update

Expected behavior

TV show artwork on Kodi should update right away just like movie artwork does.

I was surprised that I didn't find this issue posted anywhere. Is it known or only on my end?
I'll include a log file if needed.
