App Download History-Which mobile assistants can download the version history of the app? Which mobile assistants can only provide the update information of the previous version of the software in the app store, and do not provide the download of the old version of the software?
Many useful softwares lose some functions that people like after being updated. -_-So the newer the software, the better.
If you want to download the old software, it is recommended to install the synchronization assistant. You can choose to install the previous version of the software in the synchronization assistant in the version history.
A while ago, I wanted to turn off the shortcut password paid by mobile phone or the broken password of Taobao mobile phone client. The new version specifically cancels the function of turning off this password. Just installed the shortcut password for closing the old Taobao mobile phone client with the synchronization assistant. If there is no need to escape, mine will not escape.
