The problem
I was testing honestly, but the system around me was not honest.
In the exchange groups, everyone promised to help each other. But there was no real proof that people installed the app, opened it daily, kept it for the required time, or completed the testing cycle.
Some testers disappeared. Some opened the app once. Some asked others to test their apps but did not return the same effort. Others shared links without accountability. For a developer waiting 14 days, that is not just frustrating. It can block a launch.
I realized the issue was not only finding testers. The real issue was trust: proving that testing was real, fair, and continuous.
