I have one accepted manuscript waiting to be published. During the proof, I changed the corresponding author from me to my postdoc adivsor. Editor now asked why I made such a change.
What happened was that when I submitted my manuscript, I am the corresponding author by default. I failed to find any option to change it. So I planed to change it later on.
What shall I respond in order not to be rejected during this stage?
I am major in the theoretical relativity physics.
After nearly one week, my request finally is approved. I do not even have to fill out a form.
