Our app includes Android Auto, which I think is what causes it for us. Submitted 4 Sept, still in review.

Was only 48-72 hours until this year, where it randomly jumped to 2 weeks or longer like it still is.

It's really frustrating, and makes it very difficult to develop with, let alone reliably release features across platforms.

I suspect the same issue; I added Android Auto to my application on the latest release and the version I pushed on Sept 3th is still under review.
