I recently noticed the UI changes when editing semantic models, where I now need to switch from viewing to editing.
However, just this week, I found that when I switch to editing, the semantic model is automatically updated as a large semantic model, even when it's not actually very large. This is fine if the semantic model is in a Premium workspace.
The issue arises with semantic models in a Pro workspace—it does the same thing, causing all related reports to break. It won’t allow you to download, republish, or even open the dataset. Additionally, you can't switch it back to a small semantic model because it's in a Pro workspace.
The only workaround I’ve found is to temporarily change the workspace to Premium, switch the semantic model back to small, and then revert the workspace to Pro.
Is Power BI making semantic model editing a Premium feature, or is this just a bug for now?
