As I know there is no way for applicants to apply or extend dut to I haven't received any COPR in my portal yet.By the way, since your COPR has expired, did you try to extend its validity or apply for a new COPR?
To be honest, I am not sure about this process but there might be others in this thread who Know about it.
I tried to call the call center lot's of time but could talk to any agent due to heavy load of works or what ever they have.
