Sorry to see the crack - if they used rebound in the cove and used a flash coat on top of the rebound -which it looks like they may have done from the picturesaniceone said:I was hoping I was seeing things, but no - there it is, a crack on the bottom to wall transition curve .
The thin section on top dried out faster than the full thickness,creating shrinkage cracks.
What may be a bigger problem is under the crack it may be rebound - which will hurt the performance of the shell.
I would suggest asking the contractor you have concerns and ask him to take some cores of the area in question

you can find pictures of what a core should look like on this site
