I think my experience is somewhat similar to yours.
Application based on: 5+ years residency, non-EU citizen.
Application received on: 16/11/2020.
Email confirming address for passport return received on: 10/02/2021.
Responded to email confirming address on same day: 10/02/2021.
I have not received my passports till now or any further communication from Citizenship. Sent a follow-up email on 9/03/2021 asking for an update but still have not received a reply to that follow-up email.
I keep hoping that the passport will just show-up any day now. I also did expect to get a tracking number emailed through to confirm it's on it's way. But it's been over a month now and I'm also quite concerned too.
Hopefully we will both get our passports back in the coming days, so we can both sleep very well after that!
