Yeah - message saying Icloud is nearly full.
My reaction - so what!
Back up to independent drives regularly, in an transportable room 15mtrs from our back door. [If home burned, the office room would not!]
I cloud must have been a default setting that got triggered somehow.
I download stuff I need of my mobile phone to my home computer. Just went from old Iphone to Samsung 9 - the shop transferred all off the Iphone to the Sammy.
