Cant get past first loading screen after update

What is meant by “seems to be updating now”? Did you succeed to download simple 26.x GB before your system “seems to be updating” or did you meant your system “seems to be downloading”?
An update download of 26.x GB is already a challenge (we’re not all connected to fibre networks with unlimited network usage contracts) but a silent update, without any sign of a software being busy to update properly is more than a challenge, it is a product design disaster.
