Yes, praying it's just an issue of not being Queen-appropriate to be sniffling & coughing on Zoom. Or of letting her rest & get her strength back; I'm sure it's no little thing to get dressed & made up just right for the camera vs just staying in her room with a cup of tea.This could be anything from she's lost her voice (a common symptom even in mild cases) to she is really very ill and the public won't be told until she recovers or not...

Queen Elizabeth tested positive for Covid-19
Britain's Queen Elizabeth will miss a planned virtual engagement today because she is still experiencing mild cold-like symptoms after testing positive for Covid-19, a spokesman for Buckingham Palace said.
The palace announced that the queen had tested positive on Sunday and would continue with light duties.
Further engagements, such as her weekly conversation with Prime Minister Boris Johnson tomorrow, will be decided upon nearer to the time.
Queen Elizabeth had continued working after she tested positive, issuing a message of condolence to the Brazilian president over flooding in his country while self-isolating at Windsor Castle yesterday.
The Queen celebrated her Platinum Jubilee of 70 years on the throne on 6 February.
She is believed to be triple vaccinated but until recently had been on doctors' orders to rest and only undertake light duties since mid-October.
She cancelled a run of major engagements, and also secretly spent a night in hospital on 20 October 2021 undergoing preliminary tests.
News of the Queen's illness came the day before Mr Johnson announced all pandemic legal curbs in England would end later this week.
On Monday he said compulsory self-isolation for positive cases would stop on Thursday, urging a shift from government intervention to personal responsibility.
The move prompted concern from scientists and accusations from opposition critics that Mr Johnson was more concerned with appeasing members of his own party angered at the curbs than protecting public health.
Queen Elizabeth resumed in-person audiences at her Windsor Castle home west of London last week.
But she complained to one attendee of suffering from stiffness and was photographed holding a walking stick.
Her eldest son Prince Charles, 73, had to pull out of a planned engagement on 10 February after testing positive for coronavirus for a second time.
It was later revealed he had met his mother two days earlier.

I've been fascinated with the Queen since I was very young. I read a book about her & her sister, combined that with my grandma's stories about our English relatives, and ignoring the obvious huge age difference would make up stories about how I was actually their long lost sibling...LOL! Much better than Disney princess fantasies IMHO. Her death when it comes, hopefully not soon, will be a very sad end of an era.
as she is "escorted" to the 2012 Olympics in London by James Bond. 
She has a sense of humor; love it!
