Notifications no longer functional – Capitals - Multiplayer Word Battle Review

The app itself is fantastic and I fully support the removal of advertisements, however, the recent update seems to have broken all notification functionality. There's no way to tell when it's your turn without compulsively opening and refreshing the app. This issue seems to be persistent across multiple devices and presents a serious hindering to consistent play.
