ggml-org/gguf-my-repo · Problem logging into gguf-my-repo although being logged in to hugging face

I have a problem logging into gguf-my-repo although being logged in to hugging face. I am on Safari browser on Apple M4. Do I need to be part / invited to the organization? am I missing something? In my account under connected apps ggml-org/gguf-my-repo is shown to have access. What am I missing? The connected app has in the first line the remark "You must be logged in to use GGUF-my-repo." Anyhow logging in again (although I am already logged in) returns again and again my login starting page with empty particulars...... Trying to convert a model results in a red letter pop-up-box stating the the same message.
What am I doing wrong?
