At last, as of 2nd week of Jan. 2022, there is some improvement. My 1st n 2nd vaccine certificates are in this apps. But I can not add my PASSPORT NUMBER into MY PROFILE in this apps as passport number IS NOT included in the design.🙈🙈 I wonder why they never thought of incorporating PASSPORT NUMBER in the profile? Dont the designer of this apps knows that PASSPORT NUMBER must be included under WHO's vaccine certificate standard n for INTERNATIONAL TRAVEL?😇🙈
