I can' set up the WhatsApp business API, nor can I do any other particular action in my Facebook developer account. This is the case for multiple days now. I haven't received any information that I have violated any rules, nor am I aware of any rules that I would have violated. I have 2FA set up as recommended in another post ,but the problem remains. There is no information what I need to do to be get out of this.

Can someone help with this? I am fully puzzled and can't move on with my job.
