Would like to know below
1) Is it the only start trigger condition you are using?
2) Can you check notification template email body and check Current Value mapping i.e. it is value at Send time or value at Start Time
3) Subscriptions : It the notification set to both Start and End or only End.
i used only start trigger.
Current Value: Value at start time
Notify Option: Event Start
Hi Bhavin,, If that's the only the start trigger then please check notification template email body to see if the correct attribute name is used or not.
If you are able to paste snap of analysis and notification then it might help to check if there are any issues with them.
