i just got my Echo Auto today and was trying to set up the device with Alexa app on my iPhone XS MAX running 13.0 (17A5565b).
I follow the following the instructions, which are listed at https://www.amazon.com/gp/help/customer/display.html/ref=hp_left_v4_sib?ie=UTF8&nodeId=GPK9YJH8QV7VLY2Y
But the Alexa app stuck at ""Turn on Bluetooth" screen" and was not moving forward, I see the Echo Auto device was paired with the iPhone in "Settings/Bluetooth".
What else I need to do to completed the setup?
The problem is solved after enabling Alexa app in iPhone "Settings --> Privacy --> Bluetooth"
