Not sync in real-time with the website. Eg: the website pedulilindungi.id had updated with the latest test data (antigen/pcr) data and certificate, whilst the app was not update even after 24hrs. A friend got positive PCR at registered lab for kemenkes, but the apps just showed green. While other got negative PCR after 7 days, the apps kept showing black, the website had his updated PCR data though, just not sync with the app.
