I have been chatting with word press helper and to date I am sure the word press app on an iPad does not support copy paste !
Update for app word press 13th march 2017 version 7.1 file size 44.8mb’s
iPad pro OS 10.2.1
26th of March 2017 iPad pro unable to copy paste from safari in to app word press.
Issue bug appears to be present in the app word press.
Has anyone else had this issue ? please comment.
