@Princy Paul - I just tested using the new UI, and was able to successfully assign the interaction to myself once I went On Queue. Although it doesn't seem like a New UI limitation, it could just be working for our org.
Can you confirm you were able to successfully assign the same waiting interaction to yourself or others when you switched to the old UI? If it worked in the old, but not in the new, I would suggest using the Feedback button to report the issue with conversation IDs. You should also then record your screen to show both the non-working and working example, and post your issue with the error you're getting in the New UI Known Issues thread.
