Testflight prompts that the beta version was not found. What is the reason for the wrong URL of this public link?

Because this is a beta version, it can't be downloaded through the public link. The URL is wrong because it was originally a download link of another invitee. If someone clicks in, the URL is wrong.

Use the TestFlight application to help developers test beta applications. Where is it, please? iPhone、iPad？ And then what? Apple TV? Version? App Store？ Download the test flight from.

To test the beta version of the application with TestFlight, you need to accept the developer's email or invitation from openurl, and prepare the test equipment.

Development team members in App Store Connect can be added as testers and have access to all internal versions of the application.

All other invited testers can access the build version provided by the developer. Developers can invite you to take the test by email or public link.

From the day the developer uploads the build, each build has a maximum of 90 days to test. Below the application name in TestFlight, you can see the remaining test days. Every time a new build version is available for testing, TestFlight will notify you and provide a description of the test content.

During the test, all in-app purchases are free.

Test multiple builds:

When viewing an application in TestFlight, by default, you will see the latest build version available for testing. However, you can still test all other build versions provided to you.

1. Enter the page of the application in TestFlight.

2. Click "Previous build".

3. Click and install the version you want to test. The selected build will replace your currently installed version.
