  +## Limitations
  +
  +The suspense exchange is not intended to work for server-side rendering suspense! This is
  +what the `ssrExchange` is intended for and it's built into the main `urql` package. The
  +`suspenseExchange` however is just intended for client-side suspense and use with
  +`<React.Suspense>`.
  +
  +The `<React.Suspense>` element currently won't even be rendered during server-side rendering,
  +and has been disabled in `react-dom/server`. So if you use `suspenseExchange` and
  +`<React.Suspense>` in your server-side code you may see some unexpected behaviour and
  +errors.
