Same situation for me this morning. It seems this update broke more things than it introduced. :/ Not being able to see the drivers and keys data is not too bad but my remote cameras view doesn’t work now either, and I am subscribed to Connect+. ?‍I got part of the spooky action: drive mode animation, ambient lighting and sounds, but my app doesn't show an option to "Get Spooky" with costumes, instead the "Drivers and Keys" section is now says "Can't load drivers" and proximity locking, waking my Rivian, remote unlocking and remote cams no longer work. I guess that's spooky- not knowing if I can get back in my car when we go camping for the weekend. I've done resets on my phone and the car infotainment. Sucks, I was really looking forward to this.
Same for meIts broken.
Just keeps coming up with "Something went wrong" when you try to add a costume.
Glad it worked out, I'm on th ephone with support. Reinstalled the app, reset my password and now I can't log into the app with the new password. Escalating.Haha! It must have known I was taking about it, because right after I posted my reply, everything started working and I have the option for spooky themes in the app.
