I’m testing OAuth for a Marketplace app (1VJAHiolROw) that is not yet public. I’m using the development Client ID and getting the error message that says **Unable to install this app without the developer’s account. Please contact the app developer to install**. We have a licensed account, I’m an admin and I created the Marketplace app so I’m not sure why I’m getting the error. **Error** Unable to install this app without the developer’s account. Please contact the app developer to install. **Which App Type (OAuth / Chatbot / JWT / Webhook)?** OAuth. **How To Reproduce (If applicable)** 1. Sign in Zoom 2. Login to my app and click on the authenticate button which opens the following link **[Error - Zoom](https://marketplace.zoom.us/authorize?client_id=X0wEcaYqQXyIaZ1GCFEX0g)…** **Which Endpoint/s?** [https://marketplace.zoom.us/authorize](https://marketplace.zoom.us/authorize) ---

Hi @zj1 Thanks for sharing more details with me. Interesting, I tried using the email you shared with me and I do not see the app created under that account Did you recently transferred the app to a different user or deleted the app? ---
