-This technique works when you have an default value which makes sense - but there are occasionally cases when you do not, and in those cases `null` can feel reasonable as a default value.

 This causes the issue that you need to eliminate the `| null` in the type for context consumers. Our recommendation is to have the hook do a runtime check for it's existence and throw an error when not present:

-**Do not rely on just tainting for security.** Tainting an object doesn't prevent leaking of every possible derived value. For example, the clone of a tainted object will create a new untained object. Using data from a tainted object (e.g. `{secret: taintedObj.secret}`) will create a new value or object that is not tainted. Tainting is a layer of protection, a secure app will have multiple layers of protection, well designed APIs, and isolation patterns.

 * If a different `subscribe` function is passed during a re-render, React will re-subscribe to the store using the newly passed `subscribe` function. You can prevent this by declaring `subscribe` outside the component.
 
+* If the store is mutated during a [non-blocking transition update](/reference/react/useTransition), React will fall back to performing that update as blocking. Specifically, React will call `getSnapshot` a second time just before applying changes to the DOM. If it returns a different value than when it was called originally, React will restart the transition update from scratch, this time applying it as a blocking update, to ensure that every component on screen is reflecting the same version of the store.
+
+* It's not recommended to _suspend_ a render based on a store value returned by `useSyncExternalStore`. The reason is that mutations to the external store cannot be [marked as non-blocking transition updates](/reference/react/useTransition), so they will trigger the nearest [`Suspense` fallback](/reference/react/Suspense), replacing already-rendered content on screen with a loading spinner, which typically makes a poor UX.
+
+  For example, the following are discouraged:
+
+  ```js
+  const LazyProductDetailPage = lazy(() => import('./ProductDetailPage.js'));
+
+  function ShoppingApp() {
+    const selectedProductId = useSyncExternalStore(...);
+
+    // ❌ Calling `use` with a Promise dependent on `selectedProductId`
+    const data = use(fetchItem(selectedProductId))
+
+    // ❌ Conditionally rendering a lazy component based on `selectedProductId`
+    return selectedProductId != null ? <LazyProductDetailPage /> : <FeaturedProducts />;
