In short, I'm currently having two accounts with same email address, one in web and one in app, and they are not syncing with each other. I'll show you how this happened.
1. I got my new Garmin watch and downloaded Garmin Connect Mobile from App Store (China).
2. I registered an account with email (let's say the email address is email at my dot com) since it was my first time using Garmin product. I then logged in and sync with my watch, all seems fine.
3. I tried to connect my Garmin Connect account (email at my dot com) with Strava, but wierd thing happened, I couldn't. At Garmin Connect login page, I kept getting login information error.
4. I then went to Garmin Connect web page, but still couldn't get logged in with email at my dot com
5. I tried to register a new account with email at my dot com at web page, and then I succeed. And I have also successfully connected this account with Strava.
6. Now I have two seperate accounts, both with same email address email at my dot com . On iOS app, I counld see my activities and data but none of these can be seen at web page as well as Strava.
My question is, how this happened and how can I finally sync my data with Strava.
