Error: The package 'sovran-react-native' doesn't seem to be linked.

Trying to install and integrate @segment/analytics-react-native into a Expo project (not managed) and not having a lot of luck. Have followed the instructions and I keep getting the following error:

Error: The package 'sovran-react-native' doesn't seem to be linked. Make sure:

- You have run 'pod install'
- You rebuilt the app after installing the package
- You are not using Expo managed workflow

• analytics-react-native version: ^2.1.6-beta (also tried 2.1.7)
• Integrations versions (if used):
• React Native version: 0.64.3
• iOS or Android or both? ios

Steps to reproduce

• yarn add @segment/analytics-react-native @react-native-async-storage/async-storage
• yarn add @segment/sovran-react-native
• cd ios && pod install
• expo start -c

Expected behavior

Expect my app to build and for the analytics library to load up without crashing.

Actual behavior

App crashes with the following errors:

Error: The package 'sovran-react-native' doesn't seem to be linked. Make sure:
