Thank you for writing.
Following the provided information I was able to reproduce the issue you are facing with the recurring appointment. I have logged it in our feedback portal
. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item
I have also updated your Telerik points
The issue is related with complex logic for creating the appointments and calculating their start and end times according to the local settings of each machine. For the time being a workaround would not be possible. We will do our best to address the problem as soon as possible.
Should you have further questions, I would be glad to help.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
