It looks like, processing of citizenship applications is really slow due to social distancing. On the first of July was update that they still processing passports for new applicants back from 27th of March.
"As per earlier communications, applicants are asked not to submit passports/application forms, this still remains the case.
Due to the need to maintain social distancing in the workplace, passports received after the 27th March have as yet not been verified."
I am losing hope for ceremony this year. Probably Litterr was right, it might not happen
