Hi @FionaE ,
To my knowledge, Dataflow incremental refresh is only available with a Power BI Premium subscription (which is either a Premium capacity or PPU license), because you are Pro license, the incremental refresh will not work, you could turn off incremental refresh on/off toggle, it should not have influence on dataset and report.
Please check whether it is caused by setting incremental refresh?
