  2. Open the KyouStudy invitation again

Troubleshooting

Do the buttons look different, or will the app not install?

I cannot see “View in TestFlight”

Finish installing TestFlight, then reopen the invitation in Safari. If the link opened inside a messaging app, use its share menu and choose “Open in Safari.”

The invitation says it is unavailable

The test may be full, or the current build may have expired. Try again later. If it continues, email a screenshot to [email protected].

The installation is stuck or very slow

Check Wi‑Fi or mobile data and your available device storage. Fully close TestFlight, reopen it, and press “Install” again; the download will usually resume.

How do I report a bug while using the app?

Email [email protected] with what happened, the steps to reproduce it, your device model, OS version and app version. Include a screenshot of the issue if possible.
