Why isnt my galaxy s10+ updating

[Android Central Question]

Hey guys I'm new to android so I've got lots to learn. I preordered the galaxy s10+ from AT&T. I know recently they did an update to this phone ending in ASBA. My version says ASAT but when I check for an update it states that it is up to date and nothing to download.

I'm in the same boat with my 128GB prism black version. My 512GB ceramic black version received the update last week. What version do you have?
