recently acquired 2025 Q4 e-tron. MyAudi app on iPhone won't show its connected or sync unless I'm standing next to the car. the car is 20 feet away in the garage, it doesn't sync for hours. according to MMI customer service, car uses Verizon, my iPhone is on Verizon, granted I see 1 bar on the dash icon, but my phone gets service, so not sure what the issue is. if it was a mobile "service" issue why would it sync when I'm standing next to it? coming from a VW ID4 the app always remained sync'd.
