The company introduced a new feature called TestFlight Public Link. It is responsible for how developers invite people to test future versions of their applications.
Previously, developers had to send invitations to test individually for mail. Now everything is much simpler: the developer can create only one link, by which anyone can test the program through TestFlight.
The developers are all fairly transparent: they create a link in the App Store Connect and select the necessary assembly for testing. And if programmers want to release a new build, they simply add it to the group via the App Store Connect.
Using TestFlight Public Link, you can invite up to 10,000 users. However, developers can limit the number of testers. [ 9to5 ]
