I hope you are doing well. I please need some advice on my situation.

Long story short: I received my British citizenship letter of approval (by email) from the Home Office. My concern is that the letter has my old address (the one I used to live in when I applied for the citizenship). I am currently staying at an Airbnb, hence I could not give the new address to the Home Office (not a permanent address). I am also waiting for my home to be completed but due to COVID-19 there are major delays (so I cannot give the address of an off plan home that I have not moved into yet).
My question is should I inform the Home Office or should I wait to attend a ceremony at my old Council? Thank you in advance for your help.
