1. First open the phone desktop, find the App Store, and click Enter.
2. Then search the App Store for the program name that could not be verified before.
3. Then you can find the program and open the program introduction page.
We can find the privacy policy of this program by sliding the screen up.
5. Find the word contact us in the interface and click Open.
6. Finally, enter the developer's contact interface, and you can ask him to re-apply for a visa, upload the program, and the operation will be completed.

Focusing on solving puzzles, Apple needs a little "trust" to use related issues.
Why should I trust the downloaded demo platform to use it? Will it be harmful?
As long as iphone/ Apple doesn't jailbreak, whether it's an app downloaded from its own application system or a web page download (you need trust to use it). Must abide by the security mechanism of ios, sandbox mechanism!
First of all, the ios system is written in closed code, which is different from the open code of Android. As long as Android software is interested, it can interfere with the operation of all apps on other mobile phones, including information collection.
But because ios doesn't work, as long as you don't escape, you can't do this. The sandbox mechanism perfectly separates all apps and implements the "independent operation" mode, which means that no matter how powerful the developer is, you can't do it (unless the mobile phone has escaped). A software interferes with or collects any data of B software.
Plus, ios uses a fake background mechanism, which means that Apple has no background function. Your software can't run after being cut off, and will continue to run after switching back to the interface. This is why ios doesn't need to turn off the background. But Android must close the unused software, because it is still running in the background. This is also the influence of Android card not being stuck (depending on the memory size, the larger the memory, the more software running at the same time)
What does the key demonstration platform require to install a "certificate" for?
Because, the effective download problem of app store can only be considered as effective download if the same device downloads it several times. Too many downloads have nothing to do with ranking. Software developers don't give money for nothing, but it doesn't work.
Someone once erased the data with a brush, which made it impossible for the demonstration platform to identify whether it was the first download (unlimited download, earning unit price). Therefore, the demonstration platform is optimized and certificate verification is added. The installed certificate directly identifies the mobile phone ud, that is, erasing the data can also know whether the device downloads the software for the first time. This is also a measure that is forced to prevent unruly friends.
