Azure Functions Timer Trigger with Sharing Storage Triggered by All Instances

Hi, Team.

I'm looking at this document and following the instruction:

https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer#function-apps-sharing-storage

Here's the context:

* A developer from the field asked me if we can scale out or run multiple timer trigger instances or not.
* I thought it would be theoretically possible as I know the document above.
* I started a PoC for this:
* I have one Geo-Redundant Storage Account (Australia Southeast as Primary and Australia East as Secondary)
* I have two Azure Function instances - one in Australia Southeast and the other in Australia East
* Both instances are pointing to the Geo-Redundant Storage Account
* I added the "AzureFunctionsWebHost__hostid" key to the App Settings blade of both function instances with the same GUID

Here's my question:

I'm watching the console logs from both instances. But they are triggered at the same time. According to the document, only one instance should be triggered.


I wonder if I correctly understand the document or not. If I missed something, could you please let me know?
