Samsung has released the update for the LTE variant of the Tab S3 in the Philippines, Malaysia, and Vietnam, whereas the update for the Tab A (2017) is currently seeding only in Malaysia.
It should take a week or two for the new build to reach your devices, but if you can't wait, you can try pulling the update manually by heading over to the Settings > Software update menu of your tablet.
