CocoaPods could not find compatible versions for pod "customerio-reactnative/apn"

After installing and setting up customerio-expo-plugin, I'm running into the following error when trying to build my app over Expo App Services. I've tried to reset the project/Pod cache to no avail.

[!] CocoaPods could not find compatible versions for pod "customerio-reactnative/apn":
  In Podfile:
    customerio-reactnative/apn (from `../node_modules/customerio-reactnative`)
None of your spec sources contain a spec satisfying the dependency: `customerio-reactnative/apn (from `../node_modules/customerio-reactnative`)`.
You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.
