Release 2.8.1 is available for download from the App Store. This is a recommended update for all users.
This is a minor release containing bug fixes and other improvements. The key bug fix in 2.8.1 is a re-engineering of the Twitter credentialing procedure whereby you give permission for Takedown to post live scoring results to your team Twitter account. Apple removed Twitter credentialing from iOS 11 so we're now using Twitter's Software Development Kit (SDK) to do the credentialing. Seems like an improvement based on our testing. That's probably TMI but there you have it.
Download 2.8.1 in any case and life will be better.
