A financial services firm is using a model-driven app to manage client portfolios. A business rule is configured on the Portfolio table to set a 'Review Required' flag if the portfolio's risk score exceeds 80. The business rule is scoped to 'All Forms'. A junior developer creates a new Power Automate cloud flow that updates the risk score of multiple portfolios in bulk using the Dataverse connector's 'Update a row' action. Testers report that the 'Review Required' flag is not being set by the flow. What is the most likely cause of this issue?
