Markup does not work properly in pdf-files in iBook
I used to write some text on pdf-files i iBook, using "Markup" and +Text. I can stil write with the software "pencil" in Markup, but I can't use til textbox anymore. It does not work in any pdf's.
Actually the textbox shows, but I can not write my own text in it anymore :(
It is some time since the problem suddenly occured. Maybe 6-12 month. Probably after an update...
What can I do to make i work?
iPhone 6, iOS 12
