At beginning of the month, (Nov/2021) I installed AppCake on an iPad Pro11 (iOS 15.0.2).
Everything worked fine for about a week, after that any app installed [through Appcake] were not launching, unfortunately I don't have the error message anymore.
While trying to find a situation, I delete AppCake and tried to reinstall.. and here comes the problem.
Since then I was not able to reinstall it. (Appcake source: https://www.iphonecake.com/)
Unable to Install "AppCake"
This app cannot be installed because its integrity could not be verified.
Any solution to the issue?
