When loading up Testflight, I get an error, 'Testflight is unavailable. Try again later.'
When redeeming a testflight app, Tesflight will either crash or state that the code has already been redeemed (Multiple users are seeing this).
https://developer.apple.com/system-status/ indicates that the app is working, but an issue was resolved recently - is anyone awar of any ongoing issues with Testflight?
