Sorry to bring you this annoy. But Magican's uninstall problem is happened in version 1.1.1. and be solved in version 1.1.2. If you had updated Magican to version 1.1.4, then your app have no uninstall problem. If you still not sure about that, you could email Magican support team to get further help.
Magican has updated to version 1.1.4. But I still worry about the "uninstall" problem still exist in the new version.
Has the problem fixed?
