Just grabbed your app and bought the pro version. Using series XL it loads my big libary very fast, but when I click on any tv show it says "no series information available". Any thoughts how to fix?

Then there's no tvdb id available for that series. It requires it to retrieve additional info, e.g. all episodes for that series, actors.
When scraping series the default scraper in Kodi is thetvdb.com.
