**Description**  
A user installs then uninstalls and tries to re-install our app.

**Error**  
They receive an alert “This app requires pre-approval by your account admin.” Strange as this was not presented the first time.

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
oAuth

**Which Endpoint/s?**  
[https://zoom.us/oauth2](https://zoom.us/oauth2)

**How To Reproduce (If applicable)**  
Steps to reproduce the behavior:

1. Go to [https://zoom.us/oauth2/login?client\_id=vdEnqzi4RJC5RyAX5RkZYg&response\_type=code&redirect\_uri=https%3A%2F%2Fapi.themoment.tv%2Fv1%2Fusers%2Flogin%2Fzoom&\_x\_zm\_rtaid=ocU8znZTTVm4He-IYaYqfA.1593914482501.c35ce9dbc82529e44197ce245b77478b&\_x\_zm\_rhtaid=546](https://zoom.us/oauth2/login?client_id=vdEnqzi4RJC5RyAX5RkZYg&response_type=code&redirect_uri=https%3A%2F%2Fapi.themoment.tv%2Fv1%2Fusers%2Flogin%2Fzoom&_x_zm_rtaid=ocU8znZTTVm4He-IYaYqfA.1593914482501.c35ce9dbc82529e44197ce245b77478b&_x_zm_rhtaid=546)

1. After signin, it redirects to [https://zoom.us/oauth/signin?\_rnd=1593914507206&client\_id=vdEnqzi4RJC5RyAX5RkZYg&redirect\_uri=https%3A%2F%2Fapi.themoment.tv%2Fv1%2Fusers%2Flogin%2Fzoom&response\_type=code](https://zoom.us/oauth/signin?_rnd=1593914507206&client_id=vdEnqzi4RJC5RyAX5RkZYg&redirect_uri=https%3A%2F%2Fapi.themoment.tv%2Fv1%2Fusers%2Flogin%2Fzoom&response_type=code) which shows the following msg:

- You cannot authorize the app
- This app requires pre-approval by your account admin. You may reload this page and click on “Request pre-approve”.

Hey @paul1,

Double check your permissions here and see if you allow your Zoom users to install any apps:
