The app is mostly used by big groups of students from kaplan and on the ipad app it does not allow note taking using apple pencil. The highlight on the app is Dark green . not option to change either in the pc app it is yellow. i really hope the developers can improve upon this app to make it more user friendly. especially for students when zoomed in the normal highlight function also does not work either. in a smooth device such as the apple ipad this particular app dissappoints and certainly requires more work . i hope the sync abilty to allow the highlight to be on all linked accounts would also be brought in too. For an app from adobe i sincerely hope better and sooner updates to be sent out.
