CP Analysis Suggestion feature has been added after the patch on 6/16, but the button (crossed swords button right next to the mini map) doesn't show on my UI.  I'm using iPhone, and please see below.

This system can be accessed after completing the quest 'Giant Boss' in Southeast Calpheon (Chapter 5). The icon to access the system will appear beside the mini-map.

Thank you for the response, but I have completed all quests including West Valencia region, and the knowledge is 100%.  I don't think I missed any quests.  Is this repeatable quest or main story quest?  Please advise.  Thank again.

Same Issue here. Iphone XS Max latest IOS version. Please advise.
