I recently had my app approved for the Activity API and started going through the process of registering a webhook. However, in creating my app I accidentally set it to Read Only permissions.
To register the webhook, I need to be able to write. I’ve changed my permissions over to “Read, write, and direct messages” and regenerated access tokens - however, when I try and register my webhook I still get the same error:
"Application cannot perform write actions. Contact Twitter Platform Operations through https://help.twitter.com/forms/platform."
My theory is that it perhaps takes the system a bit of time to recognise that I’ve switched over my permissions? Or do I really have to contact support about this?
