ios - testflight external status active but nothing to test -

my ios application in prerelease testing process. last day sended application itunesconnect , send invites external test group, works fine. able test application. i’m doing process other (10+) applications.

but today, clicked send invites button till no e-mail , no application test in testflight app. know solution/workaround problem? thank you.

another interesting detail when click on build number there "test information" , "testers" tabs. i'm able see external testers there, time says "internal , external testers can added in app’s prerelease section."

after few hours apple sended push notification , e-mail it. able test application. change nothing in itunesconnect site. i'm able see external tester under tester tab. (instead of writing "internal , external testers can added in app’s prerelease section")

if face same issue in future, problem @ apple side. means, patience , don't worry.

thank you.
