If you use your spouse's UCI you can see the status of both your applications, but with the principal applicant's you only see the status of that application.
Just do whatever the e-mail asks. If it says recent then I would probably get new ones done just to be safe. If you decide to use the ones you had done previously then make sure they match any requirements they have provided you.
My spouse never received a UCI number or any correspondence from CIC. Thanks again for your help!
