No, not a solution. Contacted Apple Dev support who removed the Dev account part from my Apple ID but beta options still show up. Maybe iOS 17 will fix it, suspect not. Probably only wiping phone and setting up from scratch.Did you get a meaningful response in the end? I am also in the same boat, I must have enrolled in the free developer program at one point and now I’m stuck with the developer betas being available on my devices. Not the end of the world but very annoying as I’m not interested.
