yes that's what I have seen, but it doesn't mention what date for what country which would help. if people know the date in advance then you could make sure that the battery was sufficiently charged, had to leave the last update till I charged my phone (I know its silly but I'm that sort of person).
very soon they have already released it for note 10 plus in some regions so it should be very soon probably mid jan or February time along with s10 s10e and s10 plus with a few other devices receiving one ui 3 android 11 update so very very soon it should appear on your phone could be in a week or two i don't know but thats my best guess looking at samsungs history of updates
It currently shows as releasing in February. They I have just released another in build in the beta for Note 10+ I. UK. Beta release No 4. I would guess they had a few final bugs on exynos version as snapdragon countries appear to be receiving one ui 3.
