I think you need to make sure they get your document because it is crucial for your application so providing as much information as possible. And I wonder how will they know about your application without the UCI or Application number. So you must have got the automated response right? Wait 2-3 more days and if you don't get another response about your document being transferred to the respective office, raise a CSE again and add application number and UCI this time for sure. I got the manual response in 2 days. Let me know if you need more help.
