Remove highlights from ibook
I don't know how to remove yellow highlights from my a text in iBooks. How?
If this is on an iPad then tap the book so that you have the icons along the top of it, and tap the icon of the 3 lines next to the Library button top left - that should take you to a screen with headings for Contentss Bookmarks Notes.
Tap Notes to list yor highlights and notes, and swipe from right-to-left across one that you want to delete and it should reveal a Delete button at its right-hand end - you will need to repeat that for each one that you want to delete.
Tap Resume at the top top left when you've finished to go back to the page that you were on.
