I wrote a little program to publish events among a group of persons sending *.ics files to them. And I need the possibility of delete events by *.ics files. But whatever I try, and I have tried al lot of things, whwnever I send a Cancelmessage Lightning creates a new Event instead of deleting the obsolete one. Can anyone say what might be necessary to accomplish my objective. I show below one Version of ics.files for creating and deleting events. But I have tried many others too.
By the way: I have looked at the data in the sqlite database and saw that 'Confirmed' events and canceled events have different id-values wheras all other data is exact identic. May this be a reason for my Problem?
Many thanks to everyone who can help!
