On October 4, 2024, the enterprise app we are using showed a "(app name) is no longer available" pop-up on certain devices and the app was not available. And if those users delete the app and reinstall it, "I can't install (app name) because I can't verify integrity, I can't install this app" pop up. The profile of the app was renewed in February this year, and membership, certificate, and profile were all not expired. Currently, the problem has been solved by re-deploying the app, Please tell me the cause of the phenomenon and how to take preventive measures.
