GitHub App frequently leaves from some repositories

GitHub App frequently leaves from some repositories since November and this continues to happen, this is a serious workflow disruption. As far as we can tell no one has deliberately uninstalled it. 

We checked the delivery(https://github.com/settings/apps/:app/advanced) and no webhook shows that any repository has been removed from the installation of the GitHub App.

Does anyone know the possible reasons for this issue?

Hi @v-caxian,

Thanks for being here! If you haven’t already, please contact us at git.io/c with the info so we can look into that further.

Best,

Andrea
