Refresh token getting unauthorized

[saurav-abz]

I have registered for 2 applications. The problem I am facing is as follows:

1. Connecting to Fitbit via one of the two registered application. This is working fine.

2. The same user when connecting to Fitbit via the 2nd registered application (using the same email id as point 1) works fine, but the connection with the previous application (mentioned in point 1) gets 400 error when going to refresh access tokens, saying invalid refresh token.

Can someone help me out?

Hi @saurav-abz 

Do you know if your application is using the refresh token from app 2 within app 1?   If so, this is not possible and could be the reason for the 400 error (Troubleshooting Guide).   If you believe the refresh tokens are not being shared, please private message me the 2 client IDs and a user ID who has authorized both applications but receiving a 400 when refreshing tokens.
