You can use Dataflow Gen2 with an F2 Fabric capacity in regions that support it, but all users will need Power BI Pro or PPU licenses to access the dataflows and related reports. If you want to allow free users to access Power BI content, you’ll need at least an F64 capacity.
Region support may vary, so always check if your region allows Dataflow Gen2 on F2. In summary: F2 works for Gen2 if your region supports it, but F64 is required for broader access and free-user sharing.
