This update only contain a single patch for the Google Authentication module that is used in the app. As Google recently changed their API, it affects the launching of the app and causes the app to crash.
Updating to v4.9
For those of you who have a valid license and have access to Titan, you may head over to your Titan and build the new release as usual.
As for those running on the public version, you just need to head over to your app store to download the new app.
