Characters not updating

Since the WoW 9.2 patch drop, I’ve noticed that a large percentage of the time when I log out of a character, the data doesn’t update on the API (I get back a 304) and that my character hasn’t updated on the Armory as well (pulling same data I assume). I have to login and logout a few times until it finally does update. So not sure this is directly API related, but something going on. Was hoping the restart today would help, but it just happened to me.
