The flashback part of iOS application may be a system compatibility problem. For example, if your system is upgraded and the APP is not updated for a long time and is not compatible with the latest system, then there may be flashback;

The APP itself has a time lock, and there is no option to unlock the time lock when signing a contract with Apple. In this case, when logging in to iOS, you can select the unlock function in advance to solve the flashback problem.

There is also the problem when the app is packaged, that is, the app did not notice some mistakes when packaging. There was an unprovoked crash in the operation after the iOS signature operation. In this case, you can repackage the app on the platform and regenerate the ipa file for iOS signature operation.

By the way, I also summarized some reasons why iOS apps flashed back (for reference only):

1, the system is incompatible (as mentioned earlier). If it is an application in the App Store, it is generally ok to update it. However, the application update of iOS enterprise signature is very slow. If iOS users want to update, they need to download and install again, which is relatively troublesome. Therefore, the slow update of ios enterprise signature application may lead to system incompatibility, which in turn leads to iOS flashback.

2. There are too many caches, and it is inevitable that we will generate some garbage when using ios applications. If it is not cleaned for a long time, it will lead to more and more mobile phone cards, and ios may flash back.

3. Antivirus software. Applications signed by iOS enterprises may be intercepted by anti-virus software for some reasons, causing iOS applications to flash back. I would like to remind ios users that it is best to determine the source of the application before installing the iOS enterprise signature application to avoid installing illegal applications.

4. There are problems in the packaging process of packaged applications. Some ios app may be directly packaged apps and then installed with signatures. Tempering may be caused by problems in the packaging process. Recommend repackaging.

Ios flashbacks are generally not directly related to signatures. Generally speaking, iOS signature does not directly lead to flashback. However, one disadvantage of iOS corporate signature is that it will be cancelled, which is different from flashback. Generally, you can't open the application after logging out, and you will be prompted "Unable to verify the application".

If the enterprise's signature is cancelled, it needs to be re-signed, and users can continue to use it after reinstallation. If the stability requirement is high, you can choose.
