It's been six months since the Queen died, and it was announced back in June that the then Cambridges would be moving into Adelaide Cottage.

And they did. They were living in the Cottage when the late Queen died in September.

Plenty of time for Charles to have changed his mind.

What was Charles to change his mind about? The Wales are still living in the Cottage. There was never any intention of them to move into apartments in the Castles. That's was the Media's speculation.

The questions I'm wondering about is: When did he tell William he changed his mind, before or after William sign the lease on Adelaide Cottage?

Your questions are pointless. The King never changed his mind, as he didn't have any reason to change it.
