On iPhone the Home Screen app keeps its own storage, so the code must be used inside the app. Tap the Share button (square with arrow), then Add to Home Screen. Open KoreSynk TSF from the Home Screen and paste this code on its enrollment screen:
Ask your KoreSynk administrator for an enrollment link and open it on this phone - or paste the enrollment code from that link below. Each code works on one phone only.
On iPhone, add the app to your Home Screen first, then open it from there and paste the code (the part after the # in the link). A code already used in Safari cannot be used again here.
Your session ends automatically at shift change. Sign out when you hand the phone over.
