Multiple problems with Dynamics 365 VOC

I am working with VOC on Dynamics 365 and facing below issues:

1. Responses routing, Client side, to show a hidden section/question is not working though i am sure i have configured it correctly
2. Responses routing, Sever side, to create a Distress item and assigning it to the queue is not working correctly; item is created, however assigning it to the queue doesn't take place
3. Out of a sudden the sections disappeared and only questions are displayed in the survey pages 
4. Testing the survey from a sample case that automatically trigger the survey and opening the link of the survey activity, some controls do not show as Flags inside Rating List and Stars of a rating question

If anyone faced and resolved any of these problems, please feedback.
