Hey Uwe,
I have a couple of shows that are the incorrect air time. It just so happens that it will break and fix itself over time. I followed the help guide and made sure the country of origin was correct on Tmdb as well as the air time on TvDb is correct. I sync and update over and over but the time continues to be off.
The two shows are:
Married at First Sight https://www.thetvdb.com/series/married-at-first-sight
and
Love After Lockup https://www.thetvdb.com/series/341174-show
Is my sync failing? Or might there be a bigger issue?
As I am typing I see the TvDb connection has failed. Is there a current API or sync problem?
