Fixed in version 1.0.16
Users have reported instrument panels not appearing at all after updating to 1.0.15. We have temporarily removed Cotracks from the App Store in order to minimize the damage. There's no way to revert to the previous version. We will fix the problem and release a new version ASAP. Meanwhile we recommend not to apply the update 1.0.15, even if you would have already downloaded the update in iTunes. This problem may not be present on your device. It isn't on any of our testing devices. But better not try.
Version 1.0.16 fixing this problem has been released.
Fixed in version 1.0.14
