Hi tere, Here is the situation: **This works:** I have setup my production site(eg: `www.production.com`) with the custom domain like `auth.production.com` at Auth0 dashboard. After authorizing from Auth0 it goes back to `www.production.com` successfully on all browsers and iOS devices. **This doesn’t work** However, when I test Auth0 Universal Login on my staging domain(eg: `www.staging.com`) this doesn’t work at all. Before this post, I have tried all relevant solutions: 1 Set up **rotational refresh tokens** and use `useRefreshTokens={true}` and `cacheLocation="localstorage"` in my latest Auth0 React SDK `"@auth0/auth0-react": "^1.8.0"`. > See in this link `community.auth0.com/t/silent-authorization-not-working-after-login-signup/37114` 2 Double checked on **Refresh Token Rotation** > **[Refresh Token Rotation](https://auth0.com/docs/secure/tokens/refresh-tokens/refresh-token-rotation)** > > Describes how refresh token rotation provides greater security by issuing a new refresh token with each request made to Auth0 for a new access token by a client using refresh tokens. 3 Went through **Troubleshoot Renew Tokens When Using Safari** > **[Troubleshoot Renew Tokens When Using Safari](https://auth0.com/docs/troubleshoot/authentication-issues/renew-tokens-when-using-safari)** > > Issues with token renewal in Safari when ITP is enabled. > **[Configure Cross-Origin Resource Sharing](https://auth0.com/docs/get-started/applications/set-up-cors)** > > Describes how to configure Cross-Origin Resource Sharing (CORS) for an Auth0-registered application using the Auth0 Dashboard. I made sure when I turned off **Prevent cross-site tracking** my staging domain worked. So, after all that, can you please give me some directions on `develop` and `staging` envs solutions? What if those domains are all separate without sharing the same parent domain? Do I have to purchase another tenant for different envs? I’m afraid that this is going to make the development process very complicated as I have to do data transition a lot! Or, can I have multiple custom domains for all my different envs? Thanks! ---

I think I found out the root cause: > When you call getAccessTokenSilently are you using the same audience and scope that is set in the Auth0Provider? I’ve seen in some cases that silent auth will be required because a new scope or audience is requested after the app initiates.

Link… By the way, this is definitely a new thing, as earlier this year all above worked, but somehow recently I found out we will need to pass in exact both `scope` and `audience` to `Auth0Provider`. Can can I track those software updates by the way? ---
