**Summary**  
We have successfully published our Zoom App - **Linkando** ([App Marketplace](https://marketplace.zoom.us/apps/M8gb79vBRQ-3nqVKFuwMrg)) - some time ago. Now we would like to add Webinar support. We have enabled Guest Mode and added the Webinar Scope (zoomapp:inwebinar), as described in the [documentation](https://marketplace.zoom.us/docs/zoom-apps/guides/zoom-apps-for-webinar/). However, the development version of our app still doesn’t work within Webinars.

**Issue details**  
We have added Guest mode support some time ago, then re-published the app, and now the Guest Mode works fine (both in dev and production apps). Our next goal is Webinar support. We have added the Webinar Scope (zoomapp:inwebinar), as described in the [documentation](https://marketplace.zoom.us/docs/zoom-apps/guides/zoom-apps-for-webinar/). Haven’t submitted for publish afterwards - as we need to test it in the development version of the app first. However, when I try to open the development version of the app within a Webinar, I see the “Linkando is not supported in webinars” error (see picture).

 ![Webinars issue screenshot](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/7/3/734fc47cffeab38454c32d23e941bdb1298ad7bd.png)

On this screenshot, the app is displayed in the “Webinar ready apps” list, but still won’t start within the webinar with an error. Which looks like a contradiction.

**Question**  
Is this a bug or expected behavior? Do we need to perform additional actions to get the development app running in Webinars? Do we need to re-submit the app first?

Thanks!

per @evgeny.balashov,

> How did you enable webinar support?  
> I think the issue is that if you try to install app from discovery - it is a production app that doesn’t yet have the features  
> You need to install development app using a different link, and try to open it from “my apps”  
> If that helps, you could create a new app for testing (don’t publish it), debug everything there, then transition settings to you main app and submit for review.

Hi @ash.provost !

It seems that I was following the instructions correctly, and it did work for a test app I created, but not for somehow not for Linkando app. However after updating Zoom Client and restarting I’ve finally got it working.

Thanks again!
