I’m unable to send messages using Shortcuts to WhatsApp — it suddenly stopped working. I’ve already tried all the troubleshooting steps, including offloading and reinstalling both Shortcuts and WhatsApp, updating to the latest iOS version (18.6) and the latest WhatsApp version. I’ve also tested using both contact names and phone numbers, but the issue still persists.
Maybe delete Shortcuts (all your automations might be deleted), reboot your device, then reinstall Shortcuts?
