I uninstalled this app a few times now as I have had problems with the recording of excersies. It seems to go well for a while and then starts saying "strava needs a longer activity to record" or it will be deleted. So when I excersise for 30minutes and want to end the excersise recording, it diesnt give the option. Just says delete excersise or needs a longer activity. Once kept the recorder going for 90 mintutes and it still gave me no option to end and store.
