Start by reproducing the issue on the test dapp with the Mobile app on Arbitrum and Polygon, following the listed connection and simple-send steps. Compare the Mobile result with the Extension result and identify why the benign transaction produces a Blockaid error; done means the same scan succeeds on both networks without that error.
