Hi, Dvacnt. I think that it's a problem with REVESED_CLIENT_ID variable.

Try

1. Create a new OAuth Client ID for iOS.

2. After you'll see it in the list of OAuth ids. Click on iOS OAuth ID to see the details.

3. Find the iOS URL scheme information (It's only the known ClientID, but reversed).

4. Copy this information and put in you package.json as the variable REVESED_CLIENT_ID

This should be enough to make it work.
