I think i have the same problem since more than 2 weeks.
Everytime i import comics through the web, the ipad screen fluctuate as when the comics are uploaded but then i cant find the uploaded comics nowhere..
The situation even is getting worse lately as some already uploaded comics are vanishing !!!!!
Appreciate your assistance brothers.
Same issue here since a couple of weeks, the import is randomly not working.
I have either some comics that do not want to be imported and stay in the root of the document view (in itune, app) or some are duplicated as they are stuck also in the root folder...
