Did anyone face a similar situation where their citizenship changed while waiting to get an interview slot after conditional approval? What needs to be done in this situation?

I had applied for Nexus back in Feb 2020 and had an interview scheduled for May 2020 which was cancelled due to COVID
Fast forward to today, the interviews have re-opened and have booked an appointment for tomorrow - HOWEVER, since 2020 my citizenship has changed. When I applied for Nexus back in 2020, I was a Canadian PR, but now I am a Canadian Citizen. Since my application was already conditionally approved, I dont have the option to EDIT my application it seems.

Please if anyone has any guidance or similar experience/situation to share - would much appreciate. Thanks a lot
