Unable to leave a home district / no feedback
After signing out of a home district by yourself or by an ambassador there is no feedback, so one expects the signout to be successful. However the foodsaver is shown in this bezirk again after next login.
A user should be informed to ask an ambassador to change the home district. An ambassador should at least be informed that the home district should be changed. He could also be asked if the home district should be changed, and be forwarded to the funcionality.
