        Dear Priyasha,

        The issue mentioned below is not actually a problem. The RB was triggered on 26 October. For site ATMK05_AP, there was no TR link at that time. The TR link was only inserted on 30 October, which means the site was isolated when the RB was triggered.

        The screenshot below shows the TR link and its creation date.

        The latest RB report also shows a different error for the same site.
