Hello, I am gonna test the app via testflight. I sent invitation to the developer who lives in China and he got email. and he said he clicked the link from my email and opened the testflight app.
But the testflight app said like below,
You are no longer connected to the internet.
He felt strange, he can access all of the stuff such as app store, websites as well because he is using vpn.
Here is what he sent me last night.
