Connecting to different Roav VIVA in different cars

I currently have two Roav VIVAs and two cars (one in each car.)

Should my iPhone 7+ be able to automatically connect to the Roav VIVA in each car or do I have to manually connect through the app each time I switch cars?

Every time I change cars, i find myself having to manually connect through the app.

@Ed_L Hi, thank you so much for sharing your question on Anker forum. For your information, the latest connected VIVA will auto connect with your phone. That is too say, to connect with the second VIVA, it needs to click “connect” on Roav VIVA app.
I totally understand it causes much inconvenience. We forwarded this issue to our engineers. This is a brand new product line, so we always carefully consider our customers’ opinions and will try to improve it in the future.
Thank you for your patience. If you have further issue, please feel free to contact us at support@goroav.com.
