Add comment mentioning that the author's correct group could not be determined
Following from !390 (comment 278719721), some MRs may not have group label applied because the author's correct group could not be determined.
This may happen in the following scenarios:
- MR author is a gitlab team member:
- The MR author's group is not listed in
www-gitlab-com
data/team.yml
underdepartments
- The MR author may belong to more than one teams (e.g member of one team and intern in another)
- The MR author's group is not listed in
- MR author is a community member
