I have a journal paper that requires me to enter the copyright footer. The solution here partially solved my problem.
However, the content of the footer is
Copyright~\copyright~2017 IEEE. Personal use of this material is permitted. However, permission to use this material for any other purposes must be obtained from the IEEE by sending a request to pubs-permissions@ieee.org.
which is too long to fit in one line. I tried to use line break \\ or \newline, it doesn't work. What is the correct method to break the copyright footer into multiple lines in IEEEtran? Thanks.
