LiveTrack does not reconnect after going through a mobile phone coverage blackspot

LiveTrack issue. I seem to have made the mistake of living where the mobile phone coverage is patchy. Each time I start a LiveTrack session (Samsung S5) with either my 920xt or 510 the session works as advertised until I hit that first blackspot where there is no mobile coverage. Bang, the session on the website says "connection lost" and it just does not reconnect. Live tracking doesn't seem to want to reconnect when mobile coverage is reestablished moments later? Epic fail I am afraid. Or does Garmin assume perfect mobile phone coverage?
