We are aware of an issue where Pokémon GO players who have received an invitation email to access Campfire are not able to log into the app.  These affected users can access Campfire from within Pokémon GO and we recommend the following workaround to gain access to the Campfire experience:

  1. Delete the Campfire app from your device.
  2. Open the Pokémon GO app.
  3. If you are logged into an account that has been invited to Campfire, you will see the Campfire button within Pokémon GO. Use this button to access Campfire.
