GeoGebra Widgets for iBooks Author dont's work on (iOS 11) iBooks
I upgraded iOS on iPad from version 10 to 11.
GeoGebra iBooks Widget (HTML Widget) that worked on iOS 10 iBooks does not work on iOS 11 iBooks .
HTML Widge frames gets all white and is not displayed.
Is this bug a bug in iBooks or GeoGebra Widget ?
(It seems like a problem with iBooks and iBooks Author.)
