Litchi removed from TestFlight and Litchi app not workong

Hello, I received a notification that there was an update to Litchi but when I go to TestFlight it say litchi has been removed and there is no update available to download. Tried opening the app on iOS and it’s not working. What could cause this. I don’t get to fly to often but like to use Litchi for it features.

The iOS Beta version of litchi does not work anymore.
So if you are a Beta tester, opt out of it and download/install the normal iOS version.

iOS
Purchase Litchi for iOS if you have not already done so, then send a proof of purchase (receipt email from Apple) along with the email you would like to join the beta with to support@flylitchi.com and we will add you to the beta. Please avoid sending us an @hotmail email as hotmail seems to have issues receiving invitation emails from Apple’s Testflight beta software.

Contact us again if you would like to be removed from the beta.
