First, the system versions are incompatible.

System compatibility has always been the focus of APP developers. Due to the incompatibility of the systems, there may be various problems such as jamming and flashback. If it is caused by system incompatibility, you can update the version in time and click Update in the App Store.

Second, informal channel download.

We all know that the App Store is Apple's only official download channel at present, but the App Store is very strict, and many game applications can't be put on the shelves, so there are many mobile assistants.

Many game applications used by Apple users are downloaded from mobile assistants, but because they are not official channels of Apple, the game software downloaded from mobile assistants will also be accompanied by various problems, and flashback is one of them.

So, can applications that are not available in the App Store only be downloaded from mobile assistants? No, in fact, we can directly install game software that is not available in the App Store on Apple phones by making super signatures.

Enter Haizhu Developer Center, select iOS Super Signature, and upload the Apple game installation package and the file with suffix format. Ipa, select the public pool account, and purchase 1 equipment to achieve super signature.

I hope to use direct search for my user name, and there are many great gods to answer for you.
