OK folks several things about the app:
1. The last release for Ipad has a bug and works better if launched with the device in portrait orientation.
2. The mobile app is intended for easy fast viewing and so many forum features that are custom coded aren't included. This keeps the app light and load speeds up. The spoiler is one of the features that doesn't work with the app and that prolly won't change.
3. If you are having trouble still with crashes, please uninstall the app, cycle your phone off (to clear cache) and reload the app.
We know it's not perfect and are working with the developer to resolve known issues so thanks for your patience.
