ABRP Intermittent connection

I start my Audi and the status in Apple Car Play ABRP shows ZZZ, then after a few minutes, it shows red bars as if it’s disconnected. After I start driving for a few minutes, the bars turn green and SOC is consistent. If I come to a stop, the connection bars shows red indicating that it is disconnected. Is this normal? If the car is on, should ABRP show green bars for connection?
