[keycloak-user] After keycloak upgrade offline tokens are revoked

Hi, We would to upgrade our keycloak version to latest, currently we use 1.9.3. After upgrading to version 2.3 we noticed that the offline tokens that were created before the upgrade are revoked - the below response is received. Is it a known defect ? is there any workaround ? { "error": "invalid_grant", "error_description": "Invalid refresh token" } Thanks, Haim.
