Hey there and welcome to the Samsung UK and EU Community Forum
This has been very widely discussed over the last few days on the forum. A search would have answered your question.
The rollout for S24 series devices bought in the UK from UK retailers is underway. Updates are released in batches and should be with you soon.
Unfortunately no one is able to tell you exactly when for your specific device.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
