Question: All “purchased” apps reinstall after I redownload 1 app
Please help
Hello yue_i,
Thank you for using Apple Support Communities! I understand from the information you provided that your previous purchased apps are installed on your device; I'd like to help.
While I'm not sure what could have caused this to happen, the following support article provides steps to delete apps from your device:
