Question Help - Creaking 2021 Giant TCR advanced

Sep 11, 2021
I bought a few months ago a new TCR Advanced pro disc 1 and almost from the beginning I am having this awful creaking noise. It has less than 1k miles. Has been back to shop 4 times. Last time it stayed 6 weeks while I was on a trip. Everything that can be tightened or greased has been done, I assume. Can someone from noise tell what it could be? Does anyone else have similar issue? NOTE: After taking it to shop, its quiet for about 30 miles, and then slowly the noise comes back. Few ticks at first and then all the time like in the video below.
