Thanks for the quick reply. Primal has Cashu connected as the NWC wallet, and shows a zap in the UK but nothing happens. Amethyst tries to launch a native wallet app. There is no NWC config as far as I can tell. Jumble shows an error message "Zap failed: failed to publish: Error. pow. 28 bits needed. (2)". It shows a wallet connected via NWC. Primal shows a zap in the UI, but nothing else happens. Nosotros doesn't seem to have any NWC config.
