I was wondering if anyone can help, I am having an issue trying to access my activity data for a dashboard I am building. I have tried using the refresh token given on my strava API application page and this results in a read_all_permission missing authorization error. I have seen a number of others have had this issue so I followed the fix they suggested:
Using the address to approve and take the code from the resulting address
and using that method to get a different refresh token but instead of fixing the issue that then results in a 'refresh_token', 'code': 'invalid' response when I try to request an access token.
