I am kinda struggling here, i don't know if i should go all in n8n and relevance on the side or i should take make on the side. I started learning AI automation with n8n. Should i just go in n8n for now till am expert?(Goal: setup an AI Agency)

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 :)

I’m new here. Someone care to explain to me how to get the most value out of this community in specific
