Redeem code of TestFlight app - where to get it?

The redeem code of TestFlight. So how to get it? So here is my TestFlight app. I just logged in with my Apple ID, and as you can see, I used it to test apps like LocketWidget or BeReal. To get the redeem code, you need to go to a specific app and check if they have the TestFlight program. If they do, it's usually somewhere in their settings. Here is the process:

1. Go to your account settings in the specific app.
2. Look for three dots or a similar menu option.
3. Find the TestFlight program information.
4. Submit the form to get a redeem code and redeem link.

Once you receive the redeem code and link, tapping on the link will direct you to the TestFlight app where you can participate in the testing program.

Some apps may eventually close their testing programs or remove tests, so it's essential to keep that in mind. If you need an invitation code for a specific app, consider the following steps:

1. Contact the app's support team.
2. Request the specific invitation code.

Overall, using links instead of invitation codes is preferred due to the potential bugs associated with codes. If you encounter issues or are unsure about navigating TestFlight, consider uninstalling the app, as it may lead to blocking other apps and causing glitches.
