I have just switched from ownCloud 8.2.2 to nextCloud 10.0 (step by step !)
I had problems with Agenda App : several agendas disappears after upgrade and for the ones which are still there, they were empty !
Doesn’t matter, I have tried to import ICS files of each agendas, backuped just before the upgrade.
After the ics file selection, I have this warning message :
The file contain incompatible objects with the selected agenda
And if I launch the import, after loading, I finally get this error message :
Partially imported, 149 failures
And this, for each ics files !
What’s going wrong ?
