I am currently working on my first WhatsApp chatbot using an n8n AI agent, and for quite some time now I have been facing what seems to be an unsolvable issue. Error message: The WhatsApp App ID XXXXXXX already has a webhook subscription. Delete it or use another App before executing the trigger. Due to WhatsApp API limitations, you can have just one trigger per App. There are no other apps connected to this profile or business. When testing via the API, I do receive the test message from Meta, but when I send a message myself, the trigger is not fired — even though the workflow is active. Perhaps someone who has already encountered this issue before can help me out. Thanks in advance :)
