I am missing ibooks created from pdfs on my ipad air 2 IOS 11.2.6
I am missing ibook items created from pdfs from my ipad air 2 running IOS 11.2.6. They are also missing from my Iphone 6 IOS 11.2.5. I suspect they could be items where the downloaded titles were changed in order to group topics together. This happened after upgrading to IOS 11.2.6
