After upgrading NC 11.0.2 from 11.0.1 I was unable to activate the calendar app. It showed an available update. Clicking on update does actually update the app, but for some unknow reason the updated files end up in a subfolder called calendar in the calendar folder. > apps/calendar/calendar
In the app section of my NC the update notification stays. Once I move the files into the correct location the calendar works again and shows up with the correct version in the apps section.
It already happened with the upgrade to 11.0.1 (not sure if from NC 10 or NC 11.0.0)
Is this someone else is experiencing as well? If yes, I would open a bug report.
