Well, I was hoping to find an answer from the community, but calling them at this point made sense. So I did. After about an hour and a half, they still actually couldn’t tell me! Three levels of increasingly expertise and apparently Apple never thought to clearly state whether or not the battery case would work with CarPlay. Lol. Not even internally. But props to all those people I spoke too as they were really trying to figure it out.
Eventually the engineering guy asked if the case was showing if it was charging in the car, so I went down to try again and....CarPlay came up!! So that’s was a bitter sweet moment. The guy was just totally confused and now I’m just hoping it keeps working.
I mean eat the fact that it worked at all probably means it was designed to be compatible, so I’m hoping no more problems, but I’m still shocked Apple hasn’t stated that anywhere...to anyone.
So, They’re still looking into it and are going to email me with what they can find because after that whole ordeal me and the three people I dealt with were all curious.
Glad to know I wasn’t crazy and just missing some obvious answer somewhere. With that said thanks for replying and helping me through it. :)
