This update should fix the issues that were reported to me.
Unfortuanately, I have removed the fall-back method to fetch series information. This is due to the unreliability of the series metadata for certain books provided by Kobo that was used in the newly implemented method.
The release updates are:
- Fix: Remove fall-back method for fetching series info due to its unreliability
- Fix: Check when book has invalid ISBN identifier
As usual, please post here or PM me if you find any issues with this update.
