The message "The application has not reached the shelf standard, so download service is not provided for the time being" is prompted, and the installed button is grayed out: the platform has detected a problem with the software, so in order to ensure the safety and experience of your mobile phone, download service of the software is not provided for the time being. We have feedback to the software side for optimization, and will provide download service as soon as possible after optimization.
8. Prompt that the application is incompatible or does not support downloading: It means that there are some problems with the application, which is not suitable for your mobile phone model/system for the time being. If it can't be installed compared with other mobile phones, it is an abnormal installation package. It is recommended that you download other versions and try to install them through channels such as "pea pods" APP and "APP Bao" APP. If you just can't install your own mobile phone, it may be that this application is not compatible with the mobile phone system. I suggest you back up the data and go to the service center for processing.
