Feature Issue/Question - Site Collection App Catalog

[Ali Salih]

I have a O365 development tenant with Targeted release enabled for all users. When I am trying to enable Site Collection App Catalog, (per this article) I am getting the following error.

Does this mean feature has not rolled out to my tenant yet? Rollout was supposed to be completed by end of November. Any clues?

I have just tried in my test tenant (First Release enabled) and I have been able to create the App Catalog for both modern Site Collection and a classic one

It does create it for me as well. But experienced this intermittently.

It is logged at GitHub. https://github.com/SharePoint/sp-dev-docs/issues/1132
