I got 2 smartphones (Samsung A70 and Syco RS441) . I've got GC installed on both of them. When my mobile data and my bluetooth are on the livetracking starts automatically (not always immediately) on my Samsung A70 without even having to open the app. When I do the same thing with my Syco RS441 the tracking never starts. I always have to open the app and select the tracking before the livetracking starts. Do I need to change some settings in the app or some phonesettings so the livetracking can start by just putting the mobile data and bluetooth on?
