Hi all,   We encounter an issue with refresh tokens. Each time we get a new access token, a new refresh token is provided. This works correctly, as we see the refresh token being renewed each time. We use that new refresh token when getting the next access token. 30 days after the permission is granted by our end user, the newly generated refresh token (which was generated 1 hour ago and never used) returns 'Invalid grant' when getting a new access token.   At first we thought it was an incident. But it persists month over month so we would like to know the cause and fix it.   These are our 'Offline Access Configuration' settings': - Refresh token usage: One time - Refresh tokens per user: 5 - The refresh token expiration is set to '30 days' - But will expire if not used in [disabled] - Update Access Token Claims [enabled]   Is there something wrong in our approach or settings? Do other devs experience the same issue?   Thanks! ... View more
