Some background: My area has little/no cell signal, so my phone and car are connected to WIFI. First night with my M3. I left it charging over night. Was expecting push notification to tell me when its charged, but this morning I got nothing. So I opened up the app, it just says waking up for 2-3 mins then times out. It seems to enable the “open trunk” button but nothing else in the app. I’ve moved closer to the car (to downstairs, but its still in garage), still nothing. Only way I could get the app to work was walk to the car and unlock it. Is my lack of cell coverage stopping this working? Do I need to go stand by it wake it up?
