Hi, hope you don't mind hearing from me in this thread as well.
Bought these books as EPUBS and when converting them to PDF, ZIP (then renaming as CBZ) or MOBI the text is stripped. Tried converting to KFX and the conversion fails.
Strangely,
Go, Dog, Go! displays fine in Calibre.
Are You My Mother? cuts off part of the text and image. Neither display correctly in KoReader or NeoReader on my Boox, but they open without issue in Apple Books on my Mac and open fine on the Android Kindle app after uploading the EPUBs to Send My Kindle. I can send the files if you like but don't think I should upload them as they're copyrighted.
