yes..but now i must see first how this work...over night i finally import over 180k episodes...

With which version did you get it to work?

in log file i see a really lot Warning like this:
2021-06-11 07:12:43.414 T:3532  WARNING <general>: Skipped 9 duplicate messages..
2021-06-11 07:12:43.414 T:3532  WARNING <general>: [mediaimporter.plex] unknown exception when receiving data from 'xxx' (plex://XYZ/): timed out

This is a known issue.

a couple of this:

2021-06-11 03:01:46.811 T:14692 WARNING <general>: [mediaimporter.plex] failed to retrieve item Episode 6: 亦 風 得 知 身 世 秘 密 with key /library/metadata/664448 from 'xxx' (plex://XYZ/): an integer is required (got type NoneType)

and also this:

Hm these look odd. They probably profit from the "retry on failure" functionality I added even though it it mainly intended to cover connection issues but it catches any exception. I'll try to figure out where these are coming from.
