Apologize for the caused inconvenience !
Both of these issues have already been addressed to the attention of our development team and their priority has been raised as well. If everything is fine they will be resolved this week, and the fixes will be available within one of our next internal builds.
The reason for not seeing an assigned person is because we have a private backlog that duplicates the public one and this assignment was done there.
