Received mail titled "Follow the progress of your citizenship grant application" on Oct 26. Nothings moving after that.
Not sure if more number of Physical Presence Days makes any difference or they randomly pick some apps to do extensive background checks? Can't think of any other reason for this delay while other apps with same timelines are progressing normally.
