thanks for great job.
I have tried to export to GPX and than import in Strava trough WEB browser from the phone and it works, but is too complicated.
Also I try to use your tutorial and to import directly to Strava, but I can not take TOKEN, because I am sign in in Strava with Google account. When Mi fit redirect me to Strava web page for login and taking token, it is not allowed to log in with google account, only with Strava account. It says, due to security restrictions.
