404 Error trying to get data from Power BI Dataset

woernere we are, G3 subscription.

I did happen to find this:

https://powerbi.microsoft.com/en-us/blog/reminder-announcing-the-retirement-of-data-support-for-streaming-dataflows/ 

My understanding was that Dataflows and Datasets were different things, but maybe not? We use PowerAutomate to feed responses from a large number of Forms into PowerBI Streaming Datasets, and haven't had issues (in this regard, at least) until the update. 

Here's to hoping its a glitch that'll be fixed.
