ConnectedDrive App and New i3s

I'm assuming that you are in the U.S.

When you log in to your account on the BMW Connected Drive Website, the information about your car should agree with that on the BMW Connected app.  If it agrees, then maybe the 2018 i3 communications protocol with BMW's servers has changed and needs to be fixed.  But more likely, BMW's servers aren't communicating with your i3 either because your i3 is parked in an area with weak or no AT&T cell phone signal strength or BMW's servers aren't working correctly which is a common problem unfortunately.
