 - Gesture Detector will use first native view in its subtree to recognize gestures, however if this view is used only to group its children it may get automatically [collapsed](https://reactnative.dev/docs/view#collapsable-android). Consider this example:
   <FunctionalComponents />
   If we were to remove the collapsable prop from the View, the gesture would stop working because it would be attached to a view that is not present in the view hierarchy. Gesture Detector adds this prop automatically to its direct child but it's impossible to do automatically for more complex view trees.
+
+- Using the same instance of gesture handler across multiple Gesture Detectors is not possible. Have a look at the code below:
+
+  ```jsx
+  export default function Example() {
+    const pan = Gesture.Pan();
+
+    return (
+      <View>
+        <GestureDetector gesture={pan}>
+          <View>
+            <GestureDetector gesture={pan}>
+              <View />
+            </GestureDetector>
+          </View>
+        </GestureDetector>
+      </View>
+    );
+  }
+  ```
+
+  This example will throw an error, becuse we try to use the same instance of `Pan` in two different Gesture Detectors.
