Updates (apologize for being late):
Eventually the issue was fixed on last Wednesday. The solution is the same as most other people: moving the corner window back further. The fix is okay to me, since there is not much door alignment issue either (there is when looking carefully, but it seems common when I compared with other Tesla cars in the lot).
The timeline overall was not slow: Monday morning to noon Wednesday. The interesting thing is that, the man at service department never gave me enough details, even though he knew what is going on (he must have the basic knowledge to understand what the tapes on the window mean). He always told me to "let them finish the work", without any update on progress or fix details (I was asking whether it is major or minor issue). So at 10am Wednesday morning when I was in SC, he did not want to give me any progress or details (after I explicitly asked). Then at around 12:30pm when I was in my office, he texted me they have fixed it (and still not even trying to tell me how it was fixed). I'm not trying to blame them, maybe it is their work discipline to not leak such the progress and fix details? His attitude was not bad. It is just lacking of transparency throughout the process...
