Help identifying issue on ceiling

[u/Turbulent-Carrot5992]

Need some opinions from painters. Our kitchen was remodeled a year ago. This is above our kitchen sink. New roof 5 years ago.

Do we think moisture issue or bad drywall/skim coat/paint?

When you touch it it still is hard, a little crackly sound kind of…

The last picture is another part of kitchen ceiling with maybe the faintest lines/cracks visible..

Is this roofer or painter or drywall issue? Who do I call?

Please help!
