Had the update on my phone two or three days ago. I have an S10+ XEU model.
Firmware isn't pushed to every device at the same time it appears. So it could still be in the pipeline for you?
My other half has an Active 2 that shows as still having the latest firmware installed when others have had a new update recently. Same for my Watch 3 I think.
Hopefully it updates for you. Never know, could be due to the beta program but I'm just guessing.
