Enhanced API - Dataset Refresh - Subscription doesn't send!

Hi All,

I'm kicking off dataset refreshes using the Enhanced (asynchronous) API.

Enhanced refresh with Power BI REST API - Power BI | Microsoft Docs

URL:

Body:

{"type":"Full","commitMode":"transactional","retryCount":1,"applyRefreshPolicy":true,"notifyOption":"NoNotification"}

The dataset successfully refreshes:

And I have a subscription setup to send when dataset is refreshed:

The dataset has not been called by any other process that day - which hopefully rules out the 'Once per day' limitation being the issue.

No subscription email ever sends - but the dataset is definitely updating successfully. We get subscriptions from scheduled refreshes absolutely fine. When amending the body to just {"notifyOption":"NoNotification"} in order to utilise the standard (synchronous) API, the subscription sends successsfully as well!

What am I missing about the enhanced API? Are there any admin settings that need to be enabled? Can't see anything from MSFT documentation or questions around this.

All help appreciated!

Thanks in advance,

Steve
