Thank you for your question, sir.
Since the app was first released, it has gone through more than 80 versions to improve its usability and reflect public safety measures, which change with the various orders made.
We always ensure we conduct checks and tests with Google and Apple so everything is in order before the app is updated and made available to travellers.
We've kept a set of logs of issues that needed to be corrected following updates or recommendations regarding the app's usability.
