How to delete an app and all the files relates to it on iOS device
I've delete an application on my iPhone, but when I reinstall it, it login automatically. I think it must keep my login credentials or preferences somewhere on my devices. I've tried all the ways that I found on the internet but it did not work.(like,,Go to Settings > General > iPhone Storage, press delete the app rather than uninstall it. Third party tools like iTool, uKeySoft, iPhone-cleaner, iMazing, these apps could delete or uninstall the app on iOS but they cannot delete all the files related to that application either!) And I don't want to reset and erase my iPhone just to delete some files of an app. So, are there other ways to solve the issue?
