We are currently working on Book Clubs to ensure that it is the best that it can be. During this time, anyone who is not on app version 24.1 will be unable to access Book Clubs. Unfortunately, we need to disable the previous versions because we are making some backend improvements to Book Clubs that are not backwards compatible. If for some reason you are unable to update Episode, you will still be able to access everything but Book Clubs.
We understand that this is not ideal for most players and we apologize for the frustration that is caused during this time. We encourage you to update to newer app versions as they release to ensure that you are able to get the newest features and stories in Episode.
