I was testing out dataflow endorsements and found these issues:
Unfortunately dataflows only show up when you open the workspace folder in Desktop, however they should show up at the highest level of the workspace list (otherwhise the purpose of endorsement is useless in my opinion):
The endorsements only shows up if you choose Power BI dataflows, not in Power Platform dataflows in PBI Desktop. What's the difference between those? I do see the same dataflows show up, just without endorsements.
