Hello there !
First of all, thanks for providing such an amazing app
Second, i’m really sorry if my english is not as good as yours, i’m a french guy and i try to communicate properly but sometimes… that goes wrong x)
Now, the matter of this topic : I got an error while attempting to synchronize my synology Calendar (v 2.3.2-0619 ) with DAVx5 (v18.104.22.168)
Here’s the exception lpog provided by the application : https://pastebin.com/fvBMVLk1
I can provide the ICS if necessary.
If i can provide any information just tell me. Hope you can find something…
