Q1: What is TestFlight? Is it safe to download apps through TestFlight?
TestFlight is Apple's official app testing platform, designed for developers to distribute test versions of their apps before official release. TestFlight itself is available on the App Store, and all apps distributed through TestFlight are subject to Apple's review process, making them just as safe as apps downloaded directly from the App Store.
Q2: I cannot type anything into the invitation code field in TestFlight. What should I do?
You do not need to fill in this field. The input box being unavailable is expected behavior.
Solution: Tap "Cancel" to close the dialog, then copy the download link and paste it into Safari. Safari will automatically launch TestFlight and redirect you directly to the download page.
Q3: TestFlight is showing "This beta is full." What should I do?
This message means the current testing program has reached its maximum number of participants. Each TestFlight link corresponds to an independent testing program with its own quota.
Solution: Please contact our support team and we will assist you in obtaining an available download link.
Q4: I am seeing "Unable to Install" during TestFlight installation. What should I do?
This error message ("TestFlight cannot connect to App Store Connect") is typically caused by a network issue.
Solution: Please switch to a different network (e.g. switch between Wi-Fi and mobile data) and try again.
Q5: I cannot find Pionex on the App Store. What should I do?
If your Apple ID region is not supported on the App Store, please refer to the iOS App Download Guide and download Pionex via TestFlight.
