Settings is reachable from the confirmation screen, and Back from it only unhides the screen as it was drawn. Sign & Send took the network at the click, so a transfer reviewed on Sepolia went out on mainnet after a switch in between. show() now records the chain id of the network it draws for. Sign & Send refuses with a message on the screen when the active network differs, and the send carries that chain id, so ethers will not populate it for a provider on any other network.
