Apologies for bringing this thread back to life, but I was hoping that 2.4.4 would remedy the mobile key situation but it hasn't. Recently had to bring the Volvo in for service so my wife had to survive with the lucid, and I've been fielding complaints on issues that I normally just live with-mobile key being one of them. So it turns out for me it's not just the mobile key, but also the fob that behaves the same (slow responsive-ness to proximity sensing - double tapping to open is fine). So I'm wondering what exactly is going on when a proximity event happens whether it's my mobile key or the fob. Is there a Wi-Fi or Internet related element influences? My neighborhood doesn't get the best T-Mobile reception, hence my app takes a while to wake up the car. I wonder if that's an element at play here? It's also odd that I can press the first door handle, press the send and then the third to open, and regardless of the amount of time I wait in between the three presses I have to do all three! Mobile service came to look at it, replaced the batteries and said everything was in spec (unfortunately I wasn't home to check). They are coming again next week for a seat homing issue and I'll ask them to check the proximity opening again but just wanted to get educated on what the steps are and what influences timing of opening my doors.
