Zoom App in development oauth flow is successful but the app app is not showing as installed and do not show in Zoom client

I have a Zoom App in development currently showing as in draft and shareable internally within my organisation. Until a few days ago, I was able to complete the oauth flow for both the production and development client id and my app would show in the Zoom marketplace “Added Apps” as installed in both cases in the relevant tab “Apps in Production” and “Apps in Development” and it would show in the “Apps” section of the Zoom client.
 

Since yesterday, with the app uninstalled, when I try to install the development app again I do not see the consent screen, the oauth flow succeeeds (I get a code back and exchange successfully for a token) but the app neiter appears on the marketplace under “Added Apps → “Apps in Development” nor in the Zoom Client under “Apps”.
 

I have been looking this up and so far nothing conclusive. I did ask my Admin whether a setting has been changed on their side (not sure if their is a setting that would influence this?). I was wondering if people have experienced this and what could be the cause
