Druk Trace app came across some issues and was not functioning since yesterday. This was because we released a new version the day before yesterday to solve app functionality issues and vulnerability fixes in some smartphones. The concerned team has resolved the issue and now works. However, Apple is yet to release the new updated version for iOS.
Inconvenience is caused and if the app is not functional or if there are other issues (no phone, no network, etc..), details are to be recorded in the logbook.
