Hello Fabel Media AS,
Thanks for your questions! Let me help you with them.
Is it so that deleted events wont sync with the events calendar?
That is true. At the moment if you delete an event from an external calendar then it will not sync with your Events Calendar, so it will not be deleted from there. This is a feature which we have on our long term roadmap but at the moment I cannot say when it will become reality.
when he renames his events in google calendar, it creates a new event in events calendar instead of updating it
I will investigate this, please give me some time.
Meanwhile please check what is the setting under Events > Settings > Import tab > Event Update Authority. Thanks!
Also please be so kind and share your system information with me.
Thanks and cheers,
Andras
