TypeError: React.useRef is not a function.

Expo SDK
1

Please provide the following:

  1. SDK Version: 36
  2. Platforms(Android/iOS/web/all): iOS

I’m getting this error ever since updating to SDK 36:

TypeError: React.useRef is not a function. (In 'React.useRef(false)', 'React.useRef' is undefined)

This error is located at:
    in ExpoRoot (at renderApplication.js:40)
    in RCTView (at AppContainer.js:101)
    in DevAppContainer (at AppContainer.js:115)
    in RCTView (at AppContainer.js:119)
    in AppContainer (at renderApplication.js:39)

ExpoRoot
    withExpoRoot.js:8:36
renderRoot

unstable_runWithPriority
    scheduler.development.js:643:23

runnables.appKey.run
    AppRegistry.js:116:10
runApplication
    AppRegistry.js:197:26
callFunctionReturnFlushedQueue
    [native code]:0

The React version after updating is 16.9.0 which does includes hooks, so I’m not sure why useRef is not found.

Can someone help?
